Built for $7,100 to replace a deteriorated wooden bridge. Bridge was designed as a two span deck truss, with one long span over the river and a shorter truss span providing an approach to the river span. After being abandoned, the smaller truss span collapsed.

Statement of Significance 

Written by Nathan Holth

This bridge should be considered to have an extremely high degree of historic significance as what may be the last surviving lenticular full deck truss bridge. Although the smaller approach span has collapsed, it appears that most of this span remains in place. A combination of restoration and replication could likely put this approach span back into service. The main span that remains in place appears to have outstanding historic integrity including original built-up fishbelly floor beams. The only significant element missing on the bridge appears to be the original railings.

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...

A yob jumps from the Livermore Falls Bridge, illustrating in the social media ( of of several ) that it has become a liability issue.

Also shows some good footage of the bridgework if you can forgive the young man's bad judgement.

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

My letter in the May 26 edition of the state newspaper, The Union Leader.

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.

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.

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!

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?

Union Leader March 19, 2014 article: "Group seeks to improve Livermore Falls area


Union Leader Correspondent

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.

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.

It is in Campton, none so far from the Plymouth line.

A short walk from Rt 3. I don't believe there is any signage, but there are some well used pullovers on the east side of 3 which are a bit of a landmark, which also suggest it and the Gorge do see frequent visitors.

Posted a reply to the forum under a different heading, just did not want to see this thread expand when the jist of the conversation was only tangentially tied to Livermore.

I'll trip back up to the Gorge in a month or so when the melt is done and river levels drop to normal, and both snap some better photos and check on what has become of the collapsed span.

I have been viewing and commenting on BridgeHunter.com for several years. Let me comment on a few items in response to comments from a couple people below.

1. The top half of the page is the "Bridge Page" I have not included anything against covered bridges in this section. I created an unbiased, fact-based page for the bridge here.

2. The second half of this page is the "Forum Page". This is a place where people are allowed to express comments, including opinions. Many people express views I don't agree with elsewhere on the website, however I understand this is a place for people to have different opinions.

3. I am sorry if I conveyed the idea that I have something against New Hampshire in particular. The problem with covered bridges is nationwide and due to Federal Policy. While New Hampshire's bridges may be town owned and may be preserved due to the decision made by these folks, these folks have made this decision while accepting funds from the Federal Government's National Historic Covered Bridge Preservation Act (15 bridges since 2000). There was never a National Historic Metal Truss Bridge Preservation Act for example. Non-covered bridges receive no funds. They have to beg for Transportation Enhancement Grants, or get funding from mainstream bridge funding which requires them to be on-system, meet modern loading and geometry, and have a sufficiency over 50%.

4. I have never stated that covered bridges should not be posted on BridgeHunter.com. I have never questioned adding covered bridges to BridgeHunter.com. I only merely question the proportion of tax dollars that get spent preserving covered bridges versus other historic bridge types.

Posted March 4, 2012, by Dave Andrews

I agree with Will's thoughts. There's nothing wrong with preserving the few covered bridges left, in addition to the metal trusses. The covered bridges are direct ancestors of the metal trusses, and still exhibit rare truss configurations that aren't found on any metal truss.

The forum pages are getting cluttered up with the endless diatribes against covered bridges. And there were a couple more yesterday, bashing that very attractive new covered bridge in Ohio.

I took a look at the webmaster's page describing his goals for this site, and covered bridges are included. So if they're acceptable for the site's owner, then including them is no one else's business. Nathan has his own site, which is the appropriate place for his rants.

Nathan -

You're making it hard for me to want to add photographs to this listing, with your having chosen to use it as a vehicle to again post your dislike for wooden bridges, and to do so this time, with false assumptions about my states political structure.

I cannot in good conscience, add photos to the listing and seemingly rubberstamp sentiments I do not agree with, without first speaking my own mind.

I do not understand how you have come to equate a victory for the preservation of a wooden bridge, as one in the loss column for those working to preserve other types, nor can I agree with your oft repeated claim that most wooden through truss bridges fail to retain a large percentage of original material, or that trusses constructed of other materials have a naturally superior service life to one made of wood which sees proper maintenance to its cladding. I've done preservation and maintenance work on many, and have surveyed hundreds in at least ten states and wholeheartedly disagree with both statements.

There is no long existing grand scheme preservation plan here in New Hampshire that has led to what might seem to be a disproportionate number of still existing covered bridges. In truth and in irony it is the political structure which has led both to the preservation of those bridges, and the abandonment of this one. It is our Town Meeting form of Government, that coupled with Yankee thrift. It is the people here, who decide major town expenditures in our every citizen has a say and a vote form of democracy.

With but one exception I can think of, every wooden bridge in the state is Town, not State owned, it was the people in those towns with their yea or nay, at individual Town meetings, not some faceless bureaucrat in the states capitol that chose to keep those bridges in service.

The money which built the Livermore Falls Bridge was in all probability provided to the town by the land raping Lumber Baron who built and owned a number of mills in town including one in the Gorge on the west bank of the river within sight of this bridge, all part of an infrastructure he developed to strip every cent of revenue represented in the last vast stand of timber then left in the state, in the Sandwich Range which stands to the east of town.

With the demise of that mill in the Gorge the primary purpose for the bridge also ceased to exist, and the people would have seen little reason to vote to repeatedly fund reflooring it. Just as in casting a vote to fund repair instead of replacement of a bridge, it is often the pocketbook that drives how the majority decides.

One might look at the other side of that same coin. There was not a decision to fund a replacement either, which is the only reason the truss is there to hope to save.

Are you kidding me...a Lenticular deck truss!!!

What an unbelievably amazing structure...even in it's derelict state!

What an incredible one this would be to restore...as it should be!

Mystery New Hamspire Bridge
Posted March 1, 2012, by Nathan Holth

Here is a page I have created for the bridge. Please do post additional photos.

I find it extremely disturbing that this lenticular truss bridge, which probably could be argued to be nationally significant, has been allowed to sit abandoned, and one span allowed to collapse. This bridge is as rare as or rarer than any of this state's many preserved covered bridges. It is just as deserving of preservation. Furthermore, this bridge, if restored, would retain a far higher quantity of original bridge material than most covered bridges, since the iron of this bridge does not deteriorate in the way wood does.

However the collapsed span remains and the preservation technology is available to restore even badly damaged collapsed trusses. A full restoration of both spans for pedestrian use as soon as possible is the only acceptable option I see for this bridge.
