Anna Hunt Marsh Bridge
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).

Wood plank sidewalk replaced on this span.

Right, the Navy Seabees bridge is a modern rendition of a truss bridge. What makes it almost vibration free is the deck arch design. The middle of the bridge on the roadbed is about a foot or so higher than the roadbed sitting on the footing or bridge concrete foundation.

A heavy load on the arch creates compressive stress on the roadbed deck large steel members creating a much stronger bridge. I get it a large amnount of weight is transfered to the huge upper truss by their cables atached to the deck.

That has taken out most of the vibration out of this bridge….

Yea, the NH state bridge inspector gave me that one with bridge vibrations too. He told me to go up to the new Navy Seabees a few mile north on route 9. It vibrates just like the 1921 bridge. Except it was rock solid. The Navy Seabees bridge is really a beautiful bridge.

This is really about NH not being able to fund their transportation agency…the state bridge inspectors defaulting to document and inspection falsification because they don’t want to disrupt 10,000s of people.

Obviously this bridge has problems that need to be corrected. But, I do take issue with one of Mr. Mulligan's arguments...

He is concerned about the bridge vibrating when a car goes across it. Of course it vibrates. That is what bridges do. A modern UCEB will also vibrate as weight is transferred from one section to another. All it means is that the bridge is doing its job.

If you want to try something fun, stand on the walkway with your hands on the diagonal members. You will actually feel the weight being transferred. Please be safe when doing this, and please do not violate any laws, but you will gain an appreciation for how a truss bridge functions.

Funny article. What a moron. Functionally obsolete means the bridge geometry is not equal to modern guidelines, it does not mean the bridge is deteriorated. The only thing deteriorated is this guy's brain cells.

I did find that the guy had some detail photos of the bridge showing the rust that he thinks will cause the bridge to collapse. https://plus.google.com/photos/101222802273511819990/albums/...

These photos identify isolated areas of rust and section loss. These elements do not post an imminent danger to the bridge and can be easily repaired through rehabilitation.

Here's a video of the same guy who got arrested at the Charles Dana Bridge.

Proper name of the bridge is the Anna Hunt Marsh Bridge, as it was named by the NH Legislature and governor with the approval of Hinsdale, NH and Brattleboro, Vt. town bodies. AHM was a social reformer with connections to both towns and one of the few bridges named for a woman (two others, one at Maidstone, Vt crossing and a lift bridge in Portsmouth, NH)
