The Columbia Bridge is a covered bridge, carrying Columbia Bridge Road over the Connecticut River between Columbia, New Hampshire and Lemington, Vermont. Built in 1911–12, it is one of only two New Hampshire bridges built with Howe trusses, and is one of the last covered bridges built in the historic era of covered bridge construction in both states.

The Bedell Bridge was a Burr truss covered bridge that spanned the Connecticut River between Newbury, Vermont and Haverhill, New Hampshire. Until its most recent destruction in 1979, it was, with a total length of 382 feet (116 m), the second-longest covered bridge in the United States. The bridge was divided into two spans of roughly equal length, and rested on a central pier and shore abutments constructed from mortared rough stone. The eastern abutment has been shored up by the addition of a concrete footing. The bridge was 23 feet (7.0 m) wide, with a roadway width of 18.5 feet (5.6 m). Because the state line is the western low-water mark of the Connecticut River, most of the bridge was in New Hampshire; only the western abutment is in Vermont.

The previous bridge was also a stone arch bridge, which was built in 1860 and collapsed a few months later. It was designed by William Leonard Kingsbury, a local official; its builders are not known because the town's records were destroyed in a fire.

Some of the stones were left with rough surfaces, while others were hammered smooth.
