Historic Mount Orne Covered Bridge (Lancaster, New Hampshire) / October 21, 2025 by Todd Henson

The Historic Mount Orne Covered Bridge, named for the nearby Orne Mountain, spans the Connecticut River and connects Lancaster, New Hampshire, to Lunenburg, Vermont. It was built in 1911, though an earlier bridge, called the South Lancaster Bridge, was built at the location likely between 1870 and 1885. It is more of a utilitarian bridge than some others with less in the way of aesthetic design and has been a key crossing point for many years for some industries.

Mount Orne Bridge is an example of a Howe truss, patented by William Howe in 1840. In this design, vertical supports are metal rods instead of timber, which increased the load capacity of the bridge. This is one of four Howe truss bridges in New Hampshire. It is a two span bridge with a length of 266 feet. At one point maintenance was equally shared between New Hampshire and Vermont, but when the boundary between states was moved to the Vermont side of the river New Hampshire took on the majority of costs with Vermont just maintaining the entrance and a small section on their end.

Being a utilitarian bridge, Mount Orne Bridge has been used by many trucks transporting materials across the bridge. Unfortunately, it has also been victim to many accidents with loads that were too tall, tearing up the roofing beams and supports, or too heavy, causing damage to the flooring. The sign above the entrance has the dates of 1911, the original construction date, and 1983, when major revocations occurred. But due to all the accidents it has undergone many repairs over the years. During some years signs were posted to cross at your own risk. And at other times the bridge was completely closed.

Mount Orne Covered Bridge is number 30 in the New Hampshire list of covered bridges. We visited this bridge on June 19th, 2025. It began to sprinkle while we were on the Vermont side, and while we drove through the bridge towards the New Hampshire side the rain increased.

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.

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.

Viewing the Haverhill-Bath Covered Bridge — The Haverhill-Bath Covered Bridge

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.
