Milford Swing Bridge (New Hampshire)
Posted October 15, 2017, by Elizabeth Watson (aelizabethwatson [at] gmail [dot] com)

Happy to tell everyone that the bridge was listed in the National Register of Historic Places in July of 2017, and the Town of Milford is planning a complete overhaul (under supervision of the State Historic Preservation Office). Milford is in the Freedom's Way National Heritage Area, and this bridge is listed among potential National Historic Landmarks for its rarity.

They used that "too dangerous to allow workers on the bridge to repair it" excuse to demolish this bridge's "sister span" over Lake Champlain in New York and Vermont. However, with the Lake Champlain Bridge, the reason for this excuse was due to substructure (pier) deterioration. It is not clear that this New Hampshire example suffers from the same type of deterioration. Sadly though this country seems to place little value these days on having its elected officials make truthful statements, instead rewarding those who make bombastic statements.

In what shouldn't come as any surprise given NH's recent war on metal truss bridges, even this early and iconic example of a continuous arch bridge is now under threat, with possible replacement on the horizon for 2019.

My favorite part of the article is the state senator quote of “When they were first talking about restoring the bridge, the cost was about $30 million. Now, it is up to about $42 million. Also, the bridge is in such bad shape that the work will be dangerous to the people hired to do it.”. Amazing how not fixing the problem and continuing to allow it to rot increases the cost of fixing it. Sadly it sentiments like this which allow so many bridges to be lost.

Its a little sad to see this one moving out of NH and not being able to be restored for trail use on the PRRT, but on the other hand its a very exciting prospect for this to be restored for actual railroad (albeit narrow gauge) use. I'll definitely make the haul up to Wiscasset for this one

Yes, you are correct, however the Wisconsin bridge is kind of in it's own category with regular sloped end posts that seems to have vertical end posts tacked on so that the tension members could be evenly spaced. I don't know the history or detail of the Ohio bridge.

My thought is that vertal end posts, as a standard design element, largely disappeared together with cast iron main structural elements around 1875. I consider the three I listed as closer to the remaining Fink and Bollman through trusses than the other two you listed. I'm not sure how to differentiated them. Maybe we call them 'first period' or something else to distinguish them.

We may be splitting hairs, the important thing is to celebrate this bridge's existence. I'm curious about it's history. I suspect it didn't start it's life at it's present location.

BTW, there is at least one 'first period' (by my definition) American made, vertical end post Whipple in existence outside the US.

A very impressive and utterly shocking find! Is this bridge available? Who owns it? As Art suggests this is an exceedingly rare bridge... although my count of vertical end post Whipple's (even if we exclude the in-storage Mead Avenue Bridge) is at least four including this one. The others that come to mind are: Riverside Avenue Bridge in CT, Ellis Bridge in Ohio, Dunnville Bottoms Bridge in Wisconsin.

Another day another 1860's bridge..Did I really just say that? Think Roberts WOW just WOW is appropriate .

Posted August 23, 2017, by Michael Quiet (mquiet [at] gmail [dot] com)

Here is another significant Coös County Bridge. This is quite early for a fully riveted truss bridge, a testament to the innovative nature of the Boston Bridge Works. Its certainly among the oldest riveted bridges nationally. Its also a very early (oldest extant?) example of a Baltimore truss. Tied together, these two facts make this bridge historically and technologically significant.

Aside from that though, its quite a visually appeasing bridge. All members are built up boxes on the truss web, giving it a airy and intricate look. Given the light traffic of the NHCR this bridge should be safe for the time being

Posted August 23, 2017, by Michael Quiet (mquiet [at] gmail [dot] com)

Thank you all! I too share the amazement in these finds, especially since they had managed to evade any sort of historical documentation over the years. These bridges are incredibly significant on a state, regional, and national level, so it still shocks me that no one knew about them!

Coös County turned out to be quite a treat, as there were several significant undocumented bridges aside from the already documented, but noteworthy, ones. Its a good reminder that not all the good bridges have been documented yet...There are still treasures to be had :)

Another success for New Hampshire's war on the legacy of John Storrs. With this we're pretty much down to the Anna Hunt, which will be coming up for replacement in the next few years

Given how things are going I'm getting much less optimistic about the possibility of preservation.

This is a loss on several other levels, as an increasingly rare multi-span through truss, a rare product of the American Bridge/United Bridge duo, and as a survivor (2/3rds anyways) of the flood of 1936.

Replaced with a modern galvanized truss bridge. Visited the new bridge last week. It's proponents claim it will preserve the historic character of the West Henniker enclave. The Granite State is rapidly depleting its inventory of heritage iron and steel truss bridges, listed in the Lichenstein Report. But there is not any real public support for this bridge type.

Looks like the pin migrated north of where it should be. This bridge was located adjacent to the stone arch railroad bridge, and was replaced in 1930 by the Vilas Bridge. Thus it belongs in both Chesire County NH and Windham County, VT.

Here's a picture I found showing its location, you can see the arch rings of the railroad bridge in the backround.

Ah, the good ol' Live No More Falls Bridge! I do not contest the liability, but what makes it more an issue now? I cannot believe that jumping from the bridge is a new sport- I doubt it was new when the bridge was closed two thirds of a century ago, I doubt it was unheard of when it was new 130+ years ago! Being a mite afeared of heights, I never went on the bridge myself, but it was always a pleasant swimming hole & fine place to observe the bevy of cutie beauties, local & student alike taking the sun & enjoying the fresh air.

Fun fact: In Playboy's first top ten party college picks, appearing in the October '87 issue, Plymouth State was honoured. The mill ruins were the site of the photo shoot. I can't recall if the bridge was in the background or not...

Posted February 25, 2017, by Billy Sargent (pemigewasset [at] yahoo [dot] com)

You might consider adding the PVRR- Pemigewasset Valley Rail Road (aka pumkin vine RR) as a user. Pop grew up on Winter St in Plymouth, next door to section boss Rob Woodard. I haven't heard the stories in a while, so I'm fuzzy on where the PVRR ran, but I'm fair certain it partnered with B&M somehow. I think they must have run on the line past Livermore Falls & over the buttermilk rapids this bridge spans.

Posted February 17, 2017, by Michael Quiet (mquiet [at] gmail [dot] com)

Bridge continues to be at threat for demolition, with the timetable being moved up on replacing this and its counterpart span, with construction tenativley projected for 2019-2022. This project has been moving back and forth on timing, so nothing set in stone yet.

The good news is that the new bridge will be on a completely different alignment, and at least the possibility of retaining this span for pedestrian use is on the table. This should absolutely happen, given the important historic nature of this bridge (top among them is that its one of the last Storrs designed spans left in NH)

Also noted in the article that the Vilas Bridge, a spectacular 2 span open-spandrel arch upstream, is not getting a rehabilitation anytime soon (if ever).

Does anyone know if there was any existing interior lighting within the covered bridge prior to the recent rehabilitation, and if there was, was it replaced or repaired?

If no existing lighting, then does anyone know if any interior lighting was installed at or around the time of the most recent rehabilitation, and if so, what date, and does it have sensor or timer to trigger its operation?

Baker River Bridge (New Hampshire)
Posted December 8, 2016, by Nathan Holth (webmaster [at] historicbridges [dot] org)

I'm not calling the people stupid, but instead the concept. (Replace vehicular truss bridge with pedestrian bridge). Perhaps "misguided" is a more diplomatic term? That is often the case, many times due to consulting engineers who quickly condemn an existing historic bridge and then eagerly try to sell a replacement span.

As far as having bridgehunter folks help with advocacy that is something that would be immensely helpful, but sadly most people who contribute here don't seem to have interest in doing that sort of thing (although a few do and their efforts are much appreciated and extremely valuable).

For myself, I participated as a consulting party under Section 106 for a premier work of Storrs in New Hampshire, the Sewalls Falls Bridge and in that capacity, I contributed both my knowledge of historic bridge rehabilitation, and the importance of preserving the bridge, perhaps in a new location. As you can see, the outcome was not good, and the bridge is now being turned into soup cans.

Baker River Bridge (New Hampshire)
Posted December 8, 2016, by Michael Quiet (mquiet [at] gmail [dot] com)

I'm miffed I never got to visit this one. I love the Storrs spans (and this was the only one that was a Warren pattern), as well as it being a production of the United Construction/ American Bridge Co. (which are also becoming endangered).

Now onto the fact that the replacement is a non-authentic covered Pratt truss. Being from Vermont and having grown up loving covered spans I understand the appeal of them. The fact is that most normal people *like* covered bridges. Even as far back as the 40's and 50's there was an interest in wooden spans that metal ones have never seen. They remind us of a past (real or imagined) that is agrarian and simple. They're preserved and promoted because people like them, and the people who get elected to offices (whether it be Town Boards or state government) represent that (say nothing for the tourist factor).

If we want to save these bridges, we need to inspire a similar love for metal bridges. Communities everywhere have saved (or tried to save) their metal spans (just look up the Shelburne NH with the Meadows bridge. The community wants it but can't afford to restore it). Maybe we need a bridgehunter outreach program to at least make sure people know that the old rusted bridge in their town is a historical gem worth fighting for. How many people stopped to consider that this bridge was an important piece of transportation history designed by an important NH engineer? It might not have saved this on per se, but we need to try something else. Calling them "stupid" for their preferences on forum posts certainly won't get us anywhere.

...Wait... upon further inspection of the Facebook page, it almost looks like the HISTORIC vehicle-capable truss bridge was replaced with a FOOTBRIDGE?! Please tell me I am misreading something. Please tell me the replacement bridge is at least two lanes wide to support heavy truck traffic or something. Because if they replaced a historic vehicular truss with a footbridge that would move this project into a special, highly exclusive category of stupid.

Posted December 7, 2016, by Nathan Holth (webmaster [at] historicbridges [dot] org)

It is truly sad (and stupid) to see a historic metal truss bridge demolished. It is profoundly disgusting to see contractors, crane operators, engineers, etc. go through the the effort (and substantial cost to taxpayers) to engineer a non-destructive lift of a truss span, and to simply cut the bridge up for scrap afterwards. If you have gone through the trouble to pick the bridge, then SAVE THE BRIDGE afterwards! If nothing else, place it in a park as a non-functional exhibit! Don't waste everyone's time and money doing a pick like this only to scrap it out and ship it to China to be turned into soup cans!

Perhaps the "Friends" of this bridge are in league with the "Friends" of Schell Bridge?

I have never seen a state so focused on erasing the memory of one of its most notable in-state bridge engineers. A huge thank-you to Jim Garvin, I have no doubt all Storrs bridges would have been eradicated otherwise, leaving not a trace.

The comments in Mr. Mitchell's link are quite interesting. The locals are understandably proud of the covered bridge that was moved here. It is a nice looking bridge, no doubt about it. I have gone out of my way to visit a few historic covered bridges, and I am sure that I will do so again. The locals should be proud of the installation of the bridge. Yet, the old truss would have looked nice with some repair and a coat of paint as well.

My home state of Kansas no longer has any covered bridges as the last one burned in 1958. Perhaps that is why I came to appreciate the complexities of the wrought iron and steel bridges that I saw as a youngster. Discovering 1880s and 1890s wrought iron, pin connected bridges was always fun. Someday, Americans may have the same appreciation for metal truss bridges as they do for covered bridges. We are starting to see some appreciation for them out here.

Baker River Bridge (New Hampshire)
Posted December 7, 2016, by Steve Lindsey (SteveLindsey60 [at] hotmail [dot] com)

Sad to say, but Will Truax may be right. I believe when this is all over, one Storrs Bridge has been set aside, in Henniker, NH. This was due largely to the efforts of Dr. Jim Garvin. Most truss bridges are being systematically removed. An appreciation for this bridge type never evolved in NH, unlike in neighboring Vermont. The effort to save these structure started with the late John Moore and continued through people including John Summers and Dr. Jim Garvin. We were never able to make headway.

NH is a unique state. Both parties attack heritage bridge preservation but for different reasons. One characterizes the preservation efforts as boondoggles. This was seen with Mitt Romney's "Bridge-to-Nowhere" press conference in Hillsborough. The other side works for the replaced of such spans as renewing our infrastructure. This is seen in Sen Jeanne Shaheen and Rep Anne Kuster's press conference at the site of the then soon to be replaced Seawalls Falls Bridge.

The future shows no breaking from this trend. Bridge lovers are advised to look to Vermont for surviving iron and steel heritage spans. NH does better with covered bridges, as new replicas are being built to supplement the existing examples.

Posted August 25, 2016, by Dan Schoenherr (htis2008 [at] gmail [dot] com)

As of this week it is stuck in the "up" position until final demolition. Per the demands of the US Coast Guard-insofar as it had failed in the down position and navigation takes precedence.

Curiously no mention was made of the lost potential for re-use as was described below.

Before the I-95 bridge was completed the two lift bridges in Portsmouth were capable of traffic backups halfway down to Massachusetts on a summer weekend.

Outside of the scope of this website one of the largest pre-nuclear detonations in the history of the human race took place in 1905 here to improve this waterway.

I'd known about this bridge for a while, and had just assumed it was listed here. So imagine my surprise when I was planning a work trip through the region and couldn't find it! An 1889 Berlin Iron Bridge Co. suspension bridge still in service that had been flying under the BH radar...I'm very happy to get to add this for all to enjoy!

It looks like this bridge is going to need some repairs in the coming's hoping that the community supports this significant treasure:

I agree completely.

Even the hundreds of primary reports filed from that bridge do not make it historic.

Sadly, it is almost as if the remaining Storrs spans have been targeted for removal.

My rejoinder to the Friends of Wentworth Parks and Recreation's plan to replace the 1909 steel trust bridge with one salvaged from the Wayarer Inn project. Letter in the NH Sunday News, March 2015.


March 29, 2015 ·

My letter in today's Sunday News.

What is historic?

I read with interest the attempt to salvage and repurpose the “historic” the Wayfarer Hotel foot bridge ( See: Future of historic John Goffe’s Mill bridge uncertain, March 22.) I am left wondering what is historic.

After reading the article, the only historic bridge mentioned was the old 1909 Baker River Bridge now serving as a foot bridge in Wentworth. It is a riveted steel truss bridge with elaborate steel railings. It alone is eligible for the National Trust of Preservation’s historic places designation.

Will someone explain to me why the Wayfarer bridge is historic. Did a famous politician smoke a camel on it after a press conference? Did a celebrity vomit, after drinking too many gin and tonics into the dappled water below?

The old truss Baker River bridge is to be removed this summer. That is keeping with the lack of support for saving iron and steel truss bridges in New Hampshire. Unlike Vermont, Texas, Ohio. Of course the NHDOT is going to remove it.

But please don’t call the replacement Wayfarer span “historic.” Especially since they are going to add a faux covered bridge shell to it. Trot out the Wayfarer span’s use as recycling and in keeping with sustainability canards if you must. But let’s keep this intellectually honest. Avoid diluting the meaning of the word “historic.”

The liability issue that dooms many heritage sites across New Hampshire. The site is a magnet for Plymouth State University students.

Make Henniker a bridge sanctuary

To the Editor: I read with interest the fate of Hooksett’s Lilac Bridge.

New Hampshire has done a boffo of a job removing its last historic steel and iron bridges. This feat will be complete when the Livermore Falls Pumpkinseed Bridge ruin is finally removed, for liability reasons.

Perhaps a few heritage spans should be left for future generations. The remaining steel truss bridges of Henniker should be set aside. Maybe Henniker can remain the one place left in the Granite State as a sanctuary for a once common bridge type?

This is something to consider.

My letter in the state's newspaper, the Union Leader. Unfortunately buried deep within the paper with other letters reviling Trump, Hilary. Unfortunately NH and the NHDOT has an abysmal record preserving heritage spans perhaps topped only by PennDot. This is a plea for the town of Henniker to become a historic bridge sanctuary. Apparently even this is too much for the Granite State.

Posted March 20, 2016, by Will (Bridgewright [at] gmail [dot] com)

Lots of layers to this onionskin, the spot is/was ripe with bridges, both RR and highway, with a succession of losses to highwater. The highway bridges were often owned/built by two different jurisdictions with the town line running down the middle of the island. Losses and replacement were not always concurrent - No pun intended.

Wooden RR spans were sometimes saved by leaving loaded cars in them in anticipation.

Posted March 19, 2016, by Luke

And, after giving LostBridges another look, I found a duplicate entry for the bridge, which has the type (Town), build/loss dates, and a postcard.

Posted March 19, 2016, by Luke

Royce mentions a 1920 replacement date on the entry for the successor bridge, so that's where the replacement date came from.

I've not found record of the upper being a Childs, I must have been looking at the wrong LostBridges page when adding it, considering that LostBridges doesn't have info on The Upper Bridge's type either. I'll change it to the generic "Through Truss" right away.

Posted March 19, 2016, by Will (Bridgewright [at] gmail [dot] com)

Luke -

Have you found record that the Upper was a Childs or lost in '20?

Childs are a particular area of interest for me and I'm familiar with the Penacook village in Concord and the town of Boscowen and I've not found the whats and whens for this one.

Posted March 19, 2016, by Thomas R Engel (Thosengel [at] gmail [dot] com)

I saw this old bridge in 1965 on a family trip and was struck by the rest of the bridge's being in place with the westernmost span missing; one doesn't see that sort of thing often. In 1992 I got to stay overnight at someone's farm not far away and checked the bridge out: yes, the spans were still there. A local told me that the westernmost span had collapsed under a too-heavy truck (I thought he told me this happened in 1949!) and the span had never been replaced and the other spans were just blocked off and left in place. The bridge was one-way, traffic in the other direction used a bridge further north. By the late 1990's the remaining spans were rather messily removed. Somewhere I have slides showing this bridge in 1992.

This stretch of track is open and occasionally used by the Conway Scenic Railroad. The bridge is also relatively modern, built as part of a track relocation/restoration project ca. 2002.

Anyone have an idea of what the LWM stands for here. Was an old mill or foundry. I thought it might be LW Packard but not sure

Bus driver responsible for damage to historic bridge


CORNISH — The driver of a school bus carrying a varsity girls basketball team from southern Vermont is facing charges after the oversized bus struck and damaged the Dingleton Hill Covered Bridge Friday evening.

Police said Allan Henderson, 67, of Brandon, Vermont could be charged with conduct after an accident and violations for driving an overweight and overheight vehicle across the historic wooden span.

The 78-foot bridge, posted at 12,000 pounds and 7-foot-3 inches clearance, was struck on both ends by the bus.

Police Chief Douglas Hackett said the 2013 Freightliner school bus was carrying the Otter Valley Union High School girls basketball team when the driver became lost and crossed the bridge to turn around.

The bus has a 10-foot-4-inch clearance requirement and has a "curb weight" of 31,000 pounds, Hackett said.

"I think what bothers me here is that they knew there was damage and that they didn't report it. It was extremely well labeled and they ignored that," the chief said.

Shortly after the accident was broadcast Monday on a local television channel, Cornish police received a call from the Rutland Northeast Supervisory Union bus transportation department informing police that one of its buses most likely caused the damage to the bridge Friday evening, Hackett said.

The collision smashed through a wooden beam and caused other cosmetic damage to the bridge, built in 1880 by James Tasker of New Hampshire.

Evidence at the scene indicated the vehicle had amber warning strobe lights on it. Pieces of the lights were taken as evidence, police said.

Hackett said he did not know how many students were on the bus at the time of the accident.

He said that while there was a slight chance the overweight bus might have caused the bridge to collapse into the Mill Brook, the driver used poor judgment while crossing the bridge.

"I just don't know why they would even try it. Common sense tells you that the bridge is not meant for a school bus," Hackett said.

Hackett said the town is seeking prices quotes from two bridge repair companies and that an early damage estimate was not available.

RNSU officials could not be reached for comment Thursday.

Truck attack (well, actually a school bus!):


A school bus carrying a girls’ basketball team struck and damaged a historic covered bridge in New Hampshire, police said. Cornish Police Chief Doug Hackett said 67-year-old bus driver Allan Henderson of Brandon, Vt., got lost last weekend trying to find Windsor High School in Vermont. The bus carrying the Otter Valley Girls Basketball Team crossed the bridge and tried to turn around. The bridge, posted at 6 tons and 7-foot-3 clearance, was struck on both ends by the bus, which has a 10-by-4 clearance requirement and a curb weight of up to 15 tons. Police said they are investigating a misdemeanor charge of conduct after an accident and two violations. The bridge is listed on the National Register of Historic Places. It was originally constructed in 1882. (AP)

It appears that this section of rail and bridge currently belongs to the New Hampshire Central Railroad. It also appears abandoned, as you can see from this picture of the rail east of the bridge across Dalton Road.

The name of this bridge is actually The Samuel Morey Memorial Bridge.

Thanks luke.I thought you would say that.I saw a deck cover in some of the pictures underneath the rails and ties.Is this from when it was a covered bridge?

Posted December 28, 2015, by Luke

It was suspected to be arson:

Thanks guys for all of your responses on the bridge and especially the rail being bent.Was the fire on this bridge naturally caused by a lightning strike or was it arson?Because if it was either it could cause the rail to actually warp because I worked in the metals industry and do know at very high heat steel will do that.I just never expected to see pictures like that.

Posted December 28, 2015, by Chester Gehman (gehmanc2000 [at] yahoo [dot] com)

The rails are bent due to the fire in all probability. Railroaders call this a "sun kink"--in the summertime heat, rails will expand lengthwise, and with no room to expand will cause a bend in the rail. This is an extreme example of such a kink--the fire was pretty hot. Looking closely at photo #6 we can see that spikes and tie plates are missing--pulled out when the rails bent. Remaining spikes are loose. The wheels of a train could never negotiate a bend in the rails like this without derailment.

Posted December 27, 2015, by Royce Haley

I am by no means an expert but I have visited that bridge a couple of times and I don't think the bends in those rails were cause by the fire. There doesn't appear to be a sign of fire, severe heat or soot on the top of the ties or rails. The rails are to neatly bent to be an accident. And I doubt the fire moved the spikes over on the ties to correspond with the curves. As well no other parts of the rails over the bridge are bent.


P.S. as stated earlier in the thread this is a duplicate page. I saw a duplicate page alert in the forum last year for this bridge as well.

The cladding was lost to a fire in 1980, the heat from that event also kinked the rails.

Posted December 27, 2015, by george oaakley (georgeoakley49 [at] yahoo [dot] com)

I have a couple of questions on this bridge.First,i noticed it is described as a covered bridge which by looking at the pictures it is not.Second in pictures of the bridge the railroad track is bent.doesn't look like normal track.What i'm wondering is how that track got bent like that.Any answers would be greatly appreciated.

Your observation is correct Steve, the inset and protruding stones in the fourth and fifth tiers of stonework are coincident with the encased arches in the Woods built double Town which was removed to build the Storrs designed Pratt we know and love. And with the stonework being raised in height for that previous incarnation, these are almost without doubt "Springstones" for those arches.

I wonder if you might be open to my adding your photo (with accreditation) to my history of the crossing? With it being as much about the stonework and its concurrent loss with the removal of the Sewell's Falls and the predecessor bridges that granite carried.

I seriously doubt a lenticular truss like this would be built on a public road in 1910. Also consider details like the composition of the top chord... not using channel and instead angle and plate... thats basically unheard of for such a small top chord in 1910.

I've struggled with the build date myself, but I had opted not to change it due to complications with identifying the bridges date based on my site visits and the lack of any other concrete dates about this bridge. I'm *hoping* at some point someone at the NBI had some sort of fact to base the 1910 number off of, hence my reluctant acceptance of its use.

Chester, I've also seen the suggestion that this bridge was built in 1889 put forth elsewhere, and I disagree with it due to the design elements of the bridge. Essentially, the construction method of this bridge does not fit a '89 model. The additional problem is that the methods do not fit any period from '78-1900 either, hence my hesitation to even try and estimate its fabrication date.

The first clue is the web posts, which are of a parallel configuration and connect to the upper chord on the outside. You'll find these only on models up until 1885. At this point they became tapered with the top narrowing and fitting inside the upper chord, and every example I have seen from 1886 onward to the latest extant example, the 1896 model we have in storage up here in VT, have these. The Delage farm bridge has these, as it should.

The railing also doesn't match that time frame either, and is more reminiscent of an earlier type used. Around '85 these too changed (I'm seems like they did a all around retooling at this time which coincided with the awarding of the 2nd patent on the design) with the box/cross type railing which can be seen in use on examples from the '86 Lenticular Warren truss in Grantville NY through the '99 Pennsylvania truss in Stuyvesant Falls NY. Up through '85 was the larger lattice type railing which we have here, which can be found on remaining examples like the '83 Aiken Street Bridge and, although long gone, the nearby '85 Livermore Falls Bridge had these.

So it’s an early model? Well that doesn’t fit either as there are caveats against that argument. The pins, like most components, also got a change around 1885. Prior to then, the bolt heads themselves were tiny and had a cast iron fitting behind them (I think my best detail shot for one of those can be found on the '82 Bardwells Ferry Bridge page). '85 onward had a large hexagonal nut, and these are found all the way through '99 examples. This bridge, like the Delage Farm uses the later models, and thus does not fit with this being an early example

The upper chord is built up with V lacing, which doesn't necessarily rule out an early production model, but narrows the time frame. Battens were used from the earliest known models until 1882-84 during which time V lacing took dominance (Compare the Bardwell’s Ferry Bridge with the Aiken Street Bridge for instance). An example of how this combination works is the HAER documented, and currently disassembled, Golden Hill Road Bridge, which has both the newer style pins, v lacing on its upper chord, but still has the older parallel web posts

The Endpost is completely foreign and I have no idea what to make of it. It’s not built up like standard ones, being made from I beam sections and containing X lacing (of which there are no other examples). I'm guessing it was a much later fabrication.

The location and size of the Builders plate is a curiosity. It had two, one of opposite ends of the bridge, and was a rectangular form secured by 3 bolts. This doesn’t appear on any other of the remaining examples…those having builders plate being the slightly more stylized ones seen on the Delage Farm Bridge or the older examples from Corrugated Metal Co. which, while rectangular, weren’t in this position.

So as to when this bridge was built…I can only give a few possibilities based on the fact It’s a completely unique and odd juxtaposition of styles and components. While there are no confirmed examples, I have noted that Berlin Steel Construction Co. (The successor to Berlin Iron Bridge Co.) company history states that only around 1911 did they move away from production of Lenticular truss bridges. It might just be a typo, as we have no confirmed examples of these being built by Berlin Construction Co. or even after 1896, but it still opens up the question of whether this could this have been a product of Berlin Construction. The size of the builders plates would match their standard one, as would the date (and that might explain why it doesn’t match anything from the earlier era). Or perhaps this was moved/reconstructed around the time given by NBI, at which point the plates could have been replaced and it was given a fresh set of pins. We do know that Berlin Iron Bridge Co. also resold used bridges during their time, so perhaps this was a the case here and it also received a rehab at that point.

Of course there are several caveats to all of this…the Bridge was rehabbed in 1999 and we have no idea what was changed during that process. And I’ll be the first to admit that we have nowhere near a comprehensive picture of the building practices for these bridges, as we only have a small fraction remaining today of the total output of BIBCo. Perhaps reuse of older components was more common, or certain styles persisted beyond what we can tell from extant examples. However from the evidence available, I think it’s pretty clear that this bridge is not an 1889 production, nor can it be specifically pinned to any date. So thats my rational for letting the 1910 date sit....its a guess on their part, but its just as good as mine on this one.

It looks like the 1910 date came from the NBI and nobody has caught the error. Thanks for catching it. I removed the bad date.

I believe the build date of 1910 is incorrect. While it was almost definitely built by the Berlin Iron Bridge Co., it was more likely built around the same time as the Delage Bridge located a short distance away, in 1889. At any rate, Berlin stopped building lenticulars around 1895; and ceased being in existence in 1900, when it was bought out by the American Bridge Co. Unfortunately the builder's plaque is missing to clear up the mystery.

I just uploaded some pictures of this beautiful bridge that my wife and I took when we visited New Hampshire from Oregon recently. These were taken on the 18th of July, 2015. We didn't know that it was going to be demolished, there were no signs stating this at the bridge. I'm glad we got to see it, it's a shame that this piece of history is now gone forever.

I have visited this bridge twice this summer of 2015. Work has begun on the approaches. This has brought tree removal that offers a great viewing point from the east side.

My revisit was to get pictures of a feature that I noticed on my last visit but needed a telephoto lens to capture. The center pier looks to have landings for the previous structures arch trusses.

Yes the abutments and pier carried a Childs Brothers built McCallum truss bridge which was lost to high water in '07

Photos of The Rainbow clearly show braces fit to those Spring-stones.
