Historic Mechanic Street Covered Bridge (Lancaster, New Hampshire) / October 7, 2025 by Todd Henson

The town of Lancaster once had three covered bridges spanning the Israel River, which weaves its way through the town, but today only one of those remains, the Mechanic Street Covered Bridge. It was originally built in 1862, the same year the Main Street Covered Bridge was built, which garnered much more attention as it was apparently a grand covered bridge.

The Mechanic Street Covered Bridge is an example of a Paddleford truss structure, and is a single-span bridge of 94 feet. Its iconic red color stands out as you drive up Mechanic Street from either direction, and there’s a small but nice park with a bench along Pleasant Street and the banks of the Israel River.

There have been two major renovations to the bridge. In 1962, just after the bridge’s 100th anniversary, an oversized dump truck plowed into the entrance of the bridge. A sign at the bridge says that same year was the first major renovation, though the book, Covered Bridges of New Hampshire (see below), says records indicate the renovation occurred in 1967. Both the sign and the book agree that the second major renovation occurred in 2006.

Most of the details within this post were learned either from signs at the bridge or from the fantastic book, Covered Bridges of New Hampshire by Kim Varney Chandler, which I purchased from a small local shop in Lincoln while on our trip. It’s well worth it if you plan to visit the area or are just interested in covered bridges and their history and construction. The link takes you to the author’s website for the book with lots of extra information and with links to let you purchase directly from her.

The signs above the Haverhill-Bath Covered Bridge in New Hampshire show the year 1827, which is the year the bridge was planned. It wasn’t actually completed until 1829. Even so, it is the oldest covered bridge in New Hampshire and one of the oldest in North America. Unlike many other covered bridges, it’s the first and only bridge at this location, as stated on a sign inside the bridge.

In this wide view I wanted to include as much as possible so I stitched multiple wide angle photos into this panoramic image and there is a little distortion with the bridge appearing bowed in the middle, which it is not.

The Haverhill-Bath Covered Bridge is a two-span Town lattice truss, following the patent of Ithiel Town. It is the oldest Town lattice truss still in existence. It spans the Ammonoosuc River (Abenaki for “small, narrow fishing place”) just before that river flows into the Connecticut River at the village of Woodsville, part of the town of Haverhill, with the town of Bath on the other side of the Ammonoosuc.

The passing of time can be hard on wooden covered bridges, especially when they were only designed to carry the weight of a horse and buggy. Instead of replacing the bridge the two towns decided to reinforce it, adding arches between 1921-1922. They also added the pedestrian sidewalk, which I quite like as it completely separates pedestrians from automotive traffic. But by 1999 it was time to completely remove automotive traffic from the bridge, so the nearby Raymond S. Burton Bridge was constructed. Thankfully, the towns have continued to maintain the covered bridge and still allow pedestrians to cross, enjoying this piece of local history.

According to a sign at the bridge, the Bath Village Covered Bridge was built in 1832 and is the longest covered bridge in New Hampshire and one of the oldest in America. It ties the West Swanzey Bridge, also built in 1832, as the 2nd oldest covered bridges in New Hampshire. It has a unique 4-span design. The sign at the bridge states it’s an outstanding example of a Burr-Arch structure, but the book, Covered Bridges of New Hampshire (see below), says it doesn’t fully follow this design and is difficult to classify.

Much has changed throughout the years, though the bridge has remained. In 1832 a rail line was built under it. This required some modifications, including raising it by a couple feet many years later, though this didn’t stop it from being hit by an over-height train in the late 1970’s. In 1893 the hydroelectric dam was built to generate electricity from the flow of the Ammonoosuc River.

As old as it is, the bridge is actually the fifth at this location, with the first having been built in 1793. But one bridge after another was destroyed, leaving us with the 5th incarnation from 1832, which thankfully has been maintained and is still in active use. It’s interesting to note the differences in cost over time. The bridge cost $3300 to build in 1832 but by 2009 it cost just under $3 million to repair it.
