Would better be described as a Moron Attack.
Work slated for the coming Summer...
This is a fixed-span bridge; the drawbridge in the drawings is further north. I've created an entry for it here: http://bridgehunter.com/nh/belknap/bh66787/
I somehow missed this, (The Banner is a free weekly handed out at Hooksett area markets) or I would've shared it here. I lived in town as a boy, and this bridge is among my earliest memories.
It's been a bad run of news for the remaining Storrs spans of late.
That's nuts! That thing is newer and probably stronger than the Lambertville - New Hope bridge.
Can Nels fix it less than the scrap and replace price?
$11.5 million to rehab this noteworthy historic bridge and only $3.3 million to reduce it to scrap metal and replace it? Were they planning on painting the rehabilitated bridge in 24 carat gold?!
Town council voted to remove it and replace it with a pedestrian / utility bridge. It is in danger of collapsing into the Merrimack River.
I came across a bit of information which had me editing an older blog entry. It also led to the collection of enough information to recently add The McGregor here.
The Blog piece, while more about the history of the crossing than that of The McGregor, it does hold additional information, not seen here on the data page.
For those interested in the history of BIBCO, it also pictures a company advertisement which seems to be the only image of this bridge where its structure can be seen in its entirety.
Of course, since it's a covered bridge, the word "renovations" is appropriate...if it were a metal truss bridge, the word "replacement" would be used instead.
Renovations under way!:
Meaningless inane letters to the editor aside...
There was unfortunate news here today that holds a bit more meaning than the words of someone who cancels out their own opinion by dismissing an entire class of bridges >
Nice work Will! I was unaware of the Briggs truss. Thanks for bringing it to light.
A slideshow of A PP presentation documenting the replication of the Moose Brook given by the parties involved in making this happen at last years 2nd National, has recently been uploaded to the net.
Both photos of the process of recreating the trusswork, (many of them mine) and Vern's work in repairing damaged castings included >
I recently corrected multiple errors on this data page.
Some may have interest in this bridge in that it is the sole recorded example of a no longer existing patent truss type.
Background information including a link to the patent office records can be found here >
Also referred as The shuttle car bridge as it carried heavily laden shuttle cars between industrial sites hence its heavy construction.
Unless it has been recently renovated, I do not believe it is passable for pedestrians.
Very interesting pictures! There used to be a lot of covered railroad bridges on railroads here in the Willamette Valley of Oregon, most of them built between the 1880s and the 1900s, but none of them survive.
Nice work Will.
For those interested in this Wooden Howe Pony, I just shared / embedded a video of the temp removal crane pick on the bridges data page.
The Snyder Brook has been closed for some months, as scour has destabilized one of the abutments. It will be swung off the abutments Friday to await stonework repair and eventual re-emplacement in the coming summer.
Closed to traffic as of December 1st
The city has put up a project website > http://www.sewallsfallsbridge.com/project-overview.html
Not owned by Corps of Engineers, state-owned bridge.

I added and corrected some information, and embedded an eighty six year old video clip to the data page, and thought I'd also add a link to this background piece >
Truck attack update:
Another truck attack:
Doesn't sound too bad this time.
FYI - this is over the Amonoosuc, not the Connecticut.
Also, it's great that the NHDOT and the MDOT are making it available for reuse. Both decks(the upper road and the lower railroad) would make great bike paths.
Hmmm... can anyone tell me how that lower raildeck drawbridge works?
BTW just added a street view of it.
Available for adaptive reuse in a new location...
REGARDING BRIDGE AVAILABLE FOR ADAPTIVE REUSE The
REGARDING BRIDGE AVAILABLE FOR ADAPTIVE REUSE The Sarah Mildred Long Bridge on U.S. Route 1 Bypass and Railroad over the Piscataqua River in Kittery, York County, Maine and Portsmouth, Rockingham County, New Hampshire is available for adaptive reuse at a new location. Prior to dismantling, Federal law requires MaineDOT, New Hampshire DOT, and the Federal Highway Administration (FHWA) to first offer the bridge to any group that could legally take possession of the bridge and maintain it, provided the group assumes all future legal and financial liability (see 23 USC 144 (5 and 6)). Costs to induce acceptance of the offer of donation may not exceed the cost to dismantle the bridge. FHWA, MaineDOT and New Hampshire DOT will work jointly to determine the most appropriate use of the existing bridge from any proposals received. The National Register-eligible 1940 Sarah Mildred Long Bridge designed by Harrington and Cortelyou is a 27 span, 2804 foot long bridge consisting of a 243 foot long vertical lift span flanked at each end by two 227 foot long warren with vertical deck truss spans. There are seven north approach spans ranging from 70 feet to 90 feet long and riveted Parker thru truss main span and a 96 foot long riveted camelback pony truss approach span. The south approach spans consist of 15 deck girder spans. If the bridge is transferred to another party, the transfer deed may include preservation covenants that require the new owner to preserve and maintain the bridge in accordance with established standards for historic bridges.

Does anyone agree that this bridge was probably located at 43.643513,-72.112888 instead of where it's presently shown?
Some of the HAER photos were obviously taken from a nearby bridge, and these coordinates are where Rte. 4 crosses the Mascoma in close proximity to one of the many rail to trail bridges in this area.
Found this, interesting but rather unfriendly terms. Also odd that it came up in a search of recent updates considering the bridge has been gone so long:
We've made some calls Tony and found the person to talk with so perhaps we can enlighten and get Nels to work. My goal for the year, and the following years, is to keep him busy on Workin' Bridges projects. We are also looking at apprenticeship training so if you know some folks that might want to WORK and LEARN by doing, then send them our way.
We can't win them all, we don't have time to do them all, but we can help.
Don't worry Tony, they will only replace the metal parts :^)
Nels actually specifically mentioned this bridge to me some time ago and said he would love to work on this. He commented that he felt lenticular truss bridges were among the most beautiful bridges ever built, and I agree completely! If anyone in this community is interested in having the bridge evaluated get in touch with Nels at www.bachsteel.com
As far as what I have seen this is the last Lenticular Deck truss remaining and is of major significance.
This sounds like a real opportunity might be in the making to save what could certainly be the centerpiece of this area. I just hope that if it comes to fruition the right engineers and contractors are called in to repair the smaller span in-kind and replicate the original railings.
I know that Nels Raynor up in Michigan would be my choice for the rebuild and he could certainly do those railings!
I see the words REPAIR, REBUILD, and RECONSTRUCT in this article, but this sure sounds like a REPLACEMENT to me!
The article lists this as the last pumpkinseed bridge in the country. Obviously, that's not the case, pumpkinseed = lenticular, no? Is it the last lenticular deck truss?
As I remember it, it was a through truss design and a magnificent entryway into downtown Plymouth. There was little support for saving it which is a surprise for me as I have heard that Plymouth University is where in the University System of NH one can take courses and acquire a certificate in historic preservation.
Latest on bridge, moneys voted.
See: "Henniker voters green-light money for bridge construction
By TIM GOODWIN
Concord Monitor staff
Sunday, March 16, 2014
(Published in print: Sunday, March 16, 2014)
Voters approved the final step to repair the Western Avenue bridge at yesterday’s Henniker town meeting – the money to fix it.
The bridge has been closed since the state deemed it unsafe in 2008, increasing traffic on the Patterson Hill bridge, which was rebuilt 20 years ago according to historic preservation requirements.
And after supporting the project since it first appeared on the warrant in 2009, voters approved a bond, 83-37, that will raise and appropriate $6.04 million for the cost to reconstruct the Western Avenue bridge. Last year, voters approved an article to cover the $384,000 associated with the design engineering portion of the project.
“We want to send a clear signal to the state and government that we intend to construct this bridge in Henniker,” said selectmen Chairman Kris Blomback before the vote.
The state Department of Transportation and Federal Bridge Aid will cover 80 percent of the construction, expected to begin in fall 2015. The town is responsible for the remaining 20 percent, or $1.20 million of the bond, but with construction more than a year away, some felt the vote should be pushed off.
“My recommendation is to wait till we have an idea of what the real bond amount will be,” said resident Jenn McCourt.
It was one of 19 articles Henniker residents passed at this year’s town meeting, only voting down one brought forward by petition..."
Study group to focus on Livermore Falls, and by extension, The Pumpkin Seed Bridge.
Union Leader March 19, 2014 article: "Group seeks to improve Livermore Falls area
By DAN SEUFERT
Union Leader Correspondent
The Livermore Falls area of Plymouth. (Courtesy)
PLYMOUTH — A group of representatives from three towns, college students at Plymouth State University, state officials and lovers of the Livermore Falls area of the Pemigewassett River are asking for public input about the future of that part of the river.
With help from the Plymouth Rotary, the Friends of the Pemi-Livermore Falls Chapter is asking for ideas for future usage of the falls area,
"It's an amazing site. To me it's as nice as anything in Franconia Notch or the Flume," said Thaddeus Guldbrandsen, PSU's vice provost for research and engagement.
The "vision session" meetings will be held Wednesday at 5:30 p.m. at the Holderness Central School and on Saturday, March 29, at 8:30 a.m.
The falls area, which is located within the towns of Plymouth, Campton and Holderness, is owned by the state. It is a popular area for swimming and sightseeing, and above the falls area is the historically important "Pumpkin Seed" bridge, the remains of a bridge erected in 1886 that was closed in 1959.
The state owns Livermore Falls and 174 adjacent acres on both sides of the river in the towns of Campton and Holderness. A December report by PSU students David Coy and James McManus identified that the area contains two beaches, and was the site of the state's first fish hatchery.
According to the report, the area has been the site of numerous mills, and the bridge is the last standing pumpkinseed bridge in the country.
In their report, the students recommended a new footbridge, repairing some of the broken fences protecting dangerous areas of the falls area, organized cleanup of the area and improved signage.
"The implementation of an offsite education program promoting stewardship of the land could help with some of the issues faced by Livermore Falls," the students said in their report.
The campaign is called "Let's Make More out of Livermore" as Rotarians are suggesting that the area be made into a state park.
The meetings will be "brainstorming sessions," according to the rotary.
They are paying $400K for it to be taken away:
Anybody want a bridge?
The fate of this bridge is now officially sealed. Sewalls Falls Bridge to be replaced starting in 2015: http://www.concordmonitor.com/home/11081732-95/council-appro...
Town Meeting time -
Two sets of townspeople to decide...
The local paper, the Concord Monitor, headquarters in its building complex on the east side bank adjacent to this bridge. The Monitor has fought tirelessly to see the bridge replaced.
New street view added
Is the the collapsed section?:
While the Bridge at Livermore falls may be an immaculate structure I have high doubts that it will ever be restored. Livermore falls is home to one of the best cliff jumping experiences around. It is a local phenomenon and on a nice day there may be anywhere from 10-50 people swimming in this area. There are 14 documented deaths mainly contributed to people jumping off this bridge. NH live free or die is a different breed. This bridge is about 65 ft above water at the base and 105 from the top yet I have seen people jump from both areas. I can admit to being one of the fellows who jump from the bottom not the top. There are additionally three cliffs you can jump from ranging from 20ft, 40ft, and 60ft high. there is also an extremely large rope swing hanging from the bridge. when one goes of this rope swing the echo of the old metal bridge can be heard from up to half a mile away and the bridge seems to just rest on the granite on both sides of the river. Having gone on this bridge I would not be surprised if this rope swing snapped in the next few years causing injury to the user. the danger of this brings up much controversy and many locals would like to take the bridge down completely. Many locals fear doing any work on this bridge above the water will affect the towns drinking water and the water coming from the highly acclaimed spring nearby. the bridge is located over what seems to be the strongest part of the Pemigewasset river that I have ever encountered. The remnants of this bridge will be there for a long time. I would love to invest in some Hydropower in this area however It will not be allowed to happen for quite some time at least 10 years.
This page contains information regarding two bridges, the historic Long lost to arson in '93 - And the two lane Long variant built to replace it in '01.
Both have two distinctly different names, though neither is SBRB, nor is either owned by the state.
Not sure I have enough information to divorce the pages, though I will try to turn up photos of the historic Long.
Now-removed road truss bridge over same river several miles south at the Hannah Duston monument in Penacook along RR. Two or three span thru truss (Pratt probably) with westernmost span gone before 1965 when first seen; amazingly still there in 1992 and later in the 1990's but removed by 2008 but piers still in river. Mystery that for decades the remaining spans were left standing and not removed; a local man told me during one visit said an overweight truck had fallen through (in the late 1940's (?)(!)) and the new highway bridge built several hundred feet upstream replaced it which itself has since been replaced.
Anyone know the complete story? I took pictures in 1992 and later but can't post them here.
It is not maintained by the State, but I take your point, and share in the opinion of whomever made the decision as to placement that it was a disrespectful, silly, and needless choice.
And alluded to that in the caption of that photo, a photo that none the less reveals the name of the bridges builder.
I see the covered up the plaque with a clearance sign. This is evidence of how little its owners care for the history of the bridge. How hard would it be to mount the sign elsewhere on the portal? I see this nonsense all the time in Pennsylvania, I see New Hampshire is no different.
The Sewall's was briefly closed earlier this week for soil compaction tests, as part of the prep for engineering the new abutments for the replacement span. I took it as a prompt and reminder to get out and shoot some photos.
I added a few of those and the name of the contracted builder to the data page.
With all the bad news surrounding the bridge of late, I thought I'd add this story and its goodtime observations which go to my fondness of and the universal decency always shown by those using one lane bridges, even busy ones.
Have a look at image 25 - The McGregor should have a data page all its own.
The Notre Dame, a bridge I had long crossed with regularity was the first large historic bridge I remember being lost. Largely because the long fight to save it played out on my local front, it was the spark that made me aware of the Preservation Community.
Perhaps of interest to some, a history I compiled of this crossing - http://bridgewright.wordpress.com/2013/03/31/a-riddles-answe...
Currently undergoing rebuilding with the intent to restore a 10-ton rating.
Based on the photo added, this is not a lenticular and is just a parker truss... and also has had load-bearing stringers added under it.
It is not over with yet by a long way.
Sorry to hear they let you go.
Note: the state prosecutor was a long time retired Hinsdale NH(my town) police officer.
Monday I returned to "court" and effectively the judge said I did no wrong doing. It was bad prosecutor instructions and communications.
The Hinsdale Police last Friday came to my house to arrest me....engineer a weekend stay for me in jail. It came from court confusion on my arraignment and the judge issuing me a warrant for my arrest because the prosecutor said I didn’t complete certain portions of the process. Monday I returned to jail and effectively the judge said I did no wrong doing. It was bad prosecutor instructions and communications.
On Friday at 1pm I got the court to withdraw the arrest warrant pending a Monday appearance. I caught this mistake utterly by chance.
Friday night two police officers appeared at my house at 8 pm to arrest me. They were keying off a rescinded court bench arrest order. The senior police officer said this was utterly shocking...he never seen an attempt to arrest somebody with such bad or totally missing foundational paperwork in all his career.
Shoot! Forgot to add that... Thanks Steve. I had to inquire about this and got some interesting facts from the people I talked to, some of which was used in the article.... :-)
Issue of vibration discussed by Jason at Bridge Hunter Chronicles... See: http://thebridgehunter.areavoices.com/2013/09/30/bridge-vibr...
It would be awesome if you two would just email one another and quit clogging up the forum with this rubbish!
“But when a few of us mentioned this was a historic civil engineering structure that powered the nearby Holman and Merriman Machine Shop, she cancelled.”
I mis-spelled McGoldrick Dam with McCormick in the NRC document...
Just so you know, Shaheen “was at” the Hinsdale 2001 dam destruction ceremony. I spent much time with her after getting by her burley state police women protection person. I showed her plumes of grayest pollution from my camera that I secretly recorded. The NHDES just gave the polluting paper mill two miles upstream of this ceremony a good bill of health and all of the top NHDES senior officials were there in Hinsdale NH. The officials were all congregating around me asking to let us see your video…questioning me after I spoke to the governor. I left no doubt, since she’d seen the videos, she would be held accountable.
The destruction of the dam serve no bona-fides or other purposes than to get free money from the state of NH and the feds…no other reason than to show phony environmental media campaign public relation spots.
This below comes from an Aug 2001 Nuclear Regulatory Commission Document in which I am memorializing my issues with the NHDES. I am basically saying the NH Department of Environmental Services, the Nuclear Regulatory Commission and the NH Department of Transportation all look exactly alike. I can’t tell one from another.
March of 2002 is when they had that near miss with Davis Bessee…
“Anyway the real reason why I'm writing is because I got another video of the Ashuelot River. I remember talking with one of your officials(NHDES) at the McCormick dam (Hinsdale, NH) with Gov. Shaheen in explaining the continuing run-off of the Lagoons: that the orange stuff we see is really just natural stuff and safe.”
So I am trying to get around the ineffective NHDES by showing Gov Shaheen plumes of pollution emanating from a local paper mill. I want her to get the Attorney General to investigate it...I am manipulating a Governor. I instigated it all from the getgo...it was a $600 million dollar fraud case and I put three or four executive in jail for a long time.
See? This is how it works.
For a template on how this works out, visit the Concord Monitor webpage (now entirely free,) search it for "Sewalls Falls" and you can trace how the project to save the Sewalls Falls bridge with a replica along side, was converted to "replacement" with a modern span. Go back three or four years and read the Monitor articles, editorials and letters-to-the-editor and witness how the preservationists were defeated.
We may have sold your aggressive activism short here. You may have frightened the NHDOT, even through it seems you were discredited seemly before the public. You may pull this off after all, with Shaheen and Kuster coming in later, as inevitably they will, when it is safe to do so.
Nothing like an "emergency" to get the voter's dander up.
But there still is two wildcards that could upset your hand.
1) Vermont has a much stronger preservation ethos and may bulk at the bon marche. (Brattleboro merchants may not cotton to having a better access to the Hinsdale Super Walmart.)
2) Memories of the Bellows Falls Bridge debacle when a dangerous bridge wouldn't collapse and embarrassed NHDOT officials. Government officials hate that more than anything else.
Still, you may prevail.
Just got a called from a selectboard member insider...
Reliable sources are saying the Hinsdale bridge committee and selectboard has been given feelers by the NHDOT that there is a 50% chance the Hinsdale bridges are going to be shutdown permanently in the next week or so...
Big NHDOT meeting on the bridges are scheduled for this Wednesday...
Send Shaheen's office an email. Write it with bended knee, hat doffed. Write as a concerned constituent about your desire to replace these bridges. Mention her good work at the Sewall Falls bridge and that you think this would garner votes here too.
Acknowledge your mistake by removing the planks and apologize. Say you were disparate. And promise to stay away from any photo op Shaheen holds in Hinsdale.
She and Kuster are powerful. You are not. But you both want the same thing. So throw in with her and Kuster. Do it their way.
That said, it might still be too late. Shaheen is notoriously skittish. A few years back they were removing a Hinsdale dam across the Ashuelot River for river-run fish with federal money. Shaheen was to attend the celebrations and reap some profile. But when a few of us mentioned this was a historic civil engineering structure that powered the nearby Holman and Merriman Machine Shop, she cancelled. She doesn't like controversy. The dam was removed without her.
"If you play your cards right"...
So how does one play my cards right?
There have never given me any hints they were my allies what so ever...
Shaheen and Kuster are your natural allies yet you refer to them as "clowns."
You attract more flies with honey than vinegar.
Shaheen and Kuster need votes in the SW part of the state too.
If you play your cards right, you can get them to bring their dog and pony show to Hinsdale too, where the Keene and Brattleboro papers as well as local radio would cover them.
It would make is easier if we had a major NH newspaper (Concord Monitor) located within a half mile of our Hinsdale bridge like the Sewell’s Falls Bridge.
Remember they have way less than half the traffic than we do at 10,000 per day…
I wrote about the Sewell’s Falls bridge way before these clowns showed up. They are playing to the high population southeast golden coast voters…we are dirt poor and a tiny population in Hinsdale. Remember it is the obstructionist mad dog Republicans behind our problems.
This is how I framed it on July 6 2013: ‘Hinsdale's Sewalls Falls Bridge”
“This concept has been practiced elsewhere, including Europe.”
If Europe is so successful, how many nuclear aircraft carriers do they have and how come they never put a man on the moon first?
They can't even drive themselves out of their depression...
There are More Effective Ways to get a Historic Bridge Demolished.
Mulligan may want to take a page from two of New Hampshire's congressional delegation.
Senator Jeanne Shaheen and Rep Annie Kuster held a press conference on the Sewalls Falls Bridge in Concord, calling for its replacement, on Sept 12, 2013. I believe the Shaheen-Kuster approach to be more effective than prying planks up from the Charles Dana Bridge's walkway and dropping them into the river.
Maybe Shaheen and Kuster would be willing to replicate their dog and pony show in Hinsdale as there is an election coming up. They need the photo ops. Ask them.
In all cases, since funding has been tight overall, inspecting and maintaining (including fixing) the bridges far outweighs replacing them. Bridges should be replaced if and only if all options of prolonging their lifespans are exhausted. This concept has been practiced elsewhere, including Europe. This is why many countries have more historic bridges than the New England states. As I said before, bridges last the longest if they are inspected properly and maintained, with parts being fixed upon demand. And they should be designed to carry appropriate volumes of traffic, which means the days of oversized and overweight vehicles have been numbered. Less means more, get it?
“department has inserted so-called catcher beams underneath the bridge's main”
I consider them making a ‘facilitative assumption”...it is a form of fraud.
So what kind of testing or prototype or model testing did they do to make sure the catcher beams would work under the worst case? Where the rubber meets the road in safety, you don’t depend on some Hoboken engineer trying to save pennies and get promoted to gin up tack welding metal to a dangerous bridge. So where is the proof the catcher beams would work?
You think this bouncing bridge article yesterday was a coincidence with our bouncing bridge discussion...I don’t think so. Thanks.
AP IMPACT: Many US Bridges Old, Risky and Rundown
WASHINGTON September 16, 2013 (AP)
Others have damaged heritage bridges this year. Mulligan's motives might be different as is the extent of the damage done. None-the-less, by his actions on the Charles Dana Bridge, he is in danger of being seen like them by the public.
Lenticular bridge in New Milford, Conn vandalized by having deck plate removed. See: http://www.vintondaily.com/news_briefs/historic-covered-brid...
Steel truss Bunker Mill Bridge's wooden deck burned. See: http://www.kcrg.com/news/local/Fate-of-Historic-Washington-C...
It is important that Mulligan learn there are other and more productive ways of protesting that are more effective than damaging public property, even if he deems his motives above reproach.
Senator Jeanne Shaheen and Representative Annie Kuster, both Democrats, have come out for demolishing the Sewalls Falls Bridge.
Republican Mitt Romney, as a presidential candidate, condemned a historic span in Hillsboro, NH previously.
Now this has become a bipartisan sport. Existing examples of New Hampshire's civil engineering heritage will continue to bother elected and appointed officials for generations to come. Expect the last historic spans to be targeted by Granite State and national politicians in the upcoming years... Until they are all removed.
“Just as punishment should be meted out to those who burned those two covered bridges this summer in the Mid-West, as well as those who set fire to the decks of steel truss bridges in the same time period, as well as those vandals who removed a metal deck plate from that lenticular bridge in Connecticut."
I never obstructed traffic. The roadway has 10,000 cars per day and the bridge walkway barely has 25 people a day who use it. My objective was to fix the walkway...the NHDOT came within 12 hours. They renailed the boards I removed...they then renailed numerous other loose and unattached boards.
My aim was to fix this bridge in the quickest way possible.
I discussed the bridge walkway problems with the Hinsdale police prior to this and wrote a unanswered letter about the loose planks to the NHDOT...both blew me off.
I love it when public involvement in a historic bridge ends up in a person harassing another source using it as a channel:
Is it me, or is he cracking? Look at the message placed in the Bridgehunter's Chronicles and tell me what you think:
You fundamentally don’t know the long problems with the NHDOT and the politicization of our NH transportation system. This guy has had repeated studies and reports about replacing thesebridge since 1978. You could have built three bridges with the cost of all these reports. We been on the ten year wish list many times in 30 years…we have been over the same territory over and over again with the dysfunction and over prescribed ten year list. Our 1921 bridge is not going to get replaced for 50 Year.
Remember the nails and screws on those planks had completely rusted away and there was nothing attaching the boards to the bridge. This is the way we in NH get the NHDOT to fix our bridges. I was the first person in the history of NH who repaired a state owned bridge, and got arrested for it to boot. Those boards were firmly nailed to the bridge next day by the NHDOT. I damage no other component of the damaged bridge.
Here is an example of how horrid the NHDOT is. On Sept 12 of last week, we local people got the treat of watching the NHDOT washing last winter’s salt off this bridge through a huge water tanker truck. What is wrong with this picture?
If this was the case, then why was it not reported right away to authorities instead of taking the law into one's hands? Scratching my head over this....
A successful nomination to the National Trust for Historic Preservation's "Eleven Endangered Places" list (2009.) The loss of this bridge is a rarity as few listees are actually lost.
It was the highest rated New Hampshire historic bridge in the state according to the Lichtenstein Report.
The Sarah Mildred Long Lift Bridge upstream is also scheduled to be replaced.
As a reporter for a Walpole weekly, I interviewed the man that bought the sections back in the 90s. He wanted to gain access to an island across some wetlands, but couldn't get the town to approve of his plans.
" ... until I got arrested with five counts and a felony. "---Mike Mulligan
Sounds to me like an appropriate response to the destruction of public property.
Just as punishment should be meted out to those who burned those two covered bridges this summer in the Mid-West, as well as those who set fire to the decks of steel truss bridges in the same time period, as well as those vandals who removed a metal deck plate from that lenticular bridge in Connecticut.
Public property "in the commons" must be defended.
If NH has a multiyear pause on “all” new school construction funding because they are in the poor house...you think our pettily bridge got a chance?
This is a national problem!
I don't see why the bridge construction firms don't fund my legal defence...the bridge project is $46 million dollars. This is the quickest way to get the contract...somebody get to bid on the contract?
$46 million dollars is peanuts to me!
With state school building aid paused, Keene trying to move forward on projects
“But it’s a tactic Keene won’t be able to use this time; as the district prepares to introduce plans to renovate each of the city’s elementary schools, the state’s building aid program remains frozen.
When that multi-year moratorium on state-supported new school construction ends, a revised system will take over that caps the amount of money available and turns what was once an open door for aid into a competition.”
Oh brother, I have been talking to lawyers lately. They have got me dazed and now I am begging for food. I hope you aren’t going to bill me for this excellent analysis like the lawyers are doing?
I kid people who came on tours with me on the bridge...I won’t allow them to come on the bridge with me if you haven’t taken your Dramamine. Most of the people felt uncomfortable with the bridge motion who came on my tours...they were surprised and many felt fear.
We have a rather large saw mill near us. These guys have 12 foot tall and I believe 10 feet long tractors log beds, and then another 12 foot high by 10 feet long trailers. I was blessing these guys before they entered the bridge in case they won the lottery directly into heaven...”in the name of the father, son and holy ghost”. Everyone was going to heaven when I was on the bridge! I got a lot...most...of these trucker to hilariously laugh with me and they all had positive thumbs heading towards the sky. I was told some trucker went out of their way to come to the Hinsdale bridges just to get blessed by the ‘halo guy” Mike Mulligan. Truckers have a wonderful sense of humor. A few chased me and was mumbling something about kicking my butt if they caught me, but those were overweight and they sucked at running.
I made a lot of local noise about all the heavy logging trucks I’d seen and absolutely no NHDOT temporary weight stations three years ago. Then most of the logging truck stopped coming across our bridges.
Lately the local media and NHDOT have been bragging about the severe weight restrictions on the bridge. See, the NHDOT cares and these guys just accept without questioning what officialdom speaks. They are freaking machines to the one. I have a CDL license and am a retired truck driver.
There are no weight limitation signs approaching the bridge for the truckers. I know the highest federal legal weight limit(without permit) of 80,000 pound can cross that bridge. So where are the weight restrictions? The bridge is designated an E-2 bridge. Basically there is a much higher state limit than the federal limit. I contend NH will allow a much higher tractor trailer legal weight on the Hinsdale’s 1921 bridge than on our Interstates even with the so called severe weight restriction.
Everything about this bridge is about vague words and tricky phrases with the officials...keeping the truth out of state and federal document. Just because there is a bridge code doesn’t mean they measure it and abide by the code. It is all “I hate the government” voluntary engineering codes and it’s unenforceable!
First, let me begin by saying I am a structural engineer. I have a degree in civil engineering and am a licensed professional engineer. I have been designing bridges for the last 13 years. Allow me to interject and address some of the technical issues being discussed here.
DESIGN LIFE: The current bridge design code in the United States for vehicular and pedestrian bridges (AASHTO) is intended to provide a nominal design life of 75 years, assuming adequate maintenance. Owners may design to a higher standard if they so choose, but in my experience most do not vary much, if at all, from the AASHTO requirements except for larger signature type bridges. Older versions of the AASHTO code provided a design life more in the range of 50 years, although I don't think it was explicitly stated. As for railroad bridges, I believe they are typically designed for a longer life, but I am not as familiar with the code governing their design (AREMA).
DEFLECTION & VIBRATION: All bridges will experience some amount of deflection under load. The repeated loading and un-loading of spans due to transient loads (truck and pedestrian) can generate the sensation of vibration, or "bouncing" as has been described here. Excessive deflection and/or vibration can cause structural issues, but it's actually not desirable primarily from a user comfort perspective. The AASHTO bridge design code indirectly addresses vibration concerns due to transient loads by limiting the allowable deflection of the superstructure. I believe AREMA addresses vibration for railroad bridges in the same way. Vibration is more perceptible by pedestrians than by passengers in vehicles, so the allowable deflection for bridges accommodating pedestrians is more stringent.
So, the short answer is yes, all bridges will deflect or "bounce" to some extent, but the design should be such that it is not enough to be overly perceptible and cause discomfort to the intended user. The issue with older bridges is often that the intended user has changed significantly, i.e., the loading has significantly increased beyond that for which it was originally designed.
Can anyone find me a quote in news media reports that I damaged other components? I didn't! My intentions were just to get the NHDOT to nail down unattached boards to the bridge. It work like a charm until I got arrested with five counts and a felony.
“and causing additional damage to the structure...
Reasonability versus Radicalism involving a pair of New Hampshire bridges
The Charles Dana and Anna Hunt Marsh Bridges are two identical green 1920 Parker through truss spans that carry NH Hwy. 119 over the Connecticut River and its island connecting Battleboro and Hinsdale. Both are considered eligible for listing on the National Register of Historic Places. But sadly both are too narrow and need to be replaced. Replacement plans have been in the works for over 20 years, but one person tried to quicken the process by vandalizing the bridge. Mike Mulligan was arrested for pulling the wooden planks from the pedestrian boardwalk and causing additional damage to the structure as a way of justifying the need to replace the bridge. He was later released with a restraining order that he stays away from the bridge and if he needs to cross it, he must not get out of the car. Mr. Mulligan recently used James Baughn’s Bridgehunter website to justify his actions, which turned into a philosophical discussion involving the bounciness and the oil for the wheel. Needless to say he did not receive any support but he is in the running for the 2013 Smith Awards in the category “Dumbest Reason to Destroy a Bridge.” A link to the Charles Dana Bridge with the dialogue in the comment section can be found here. As for the bridges themselves, they are scheduled to be replaced but plans are in the making to convert these bridges into pedestrian crossings. But it will take 3-5 years before work actually begins, given the current budget situation in New Hampshire. Sorry Mike, but you have to deal with the current situation and grin and bear it. It’s better than going to jail and paying dearly for vandalism.
Sure, on all rope bridges?
