It is one of a small number of 19th-century stone arch bridges in the state, and the only one known in central western New Hampshire.
[1] The railroad right-of-way has been functionally abandoned, and the bridge may become part of a continuation of the Northern Rail Trail.
The Stone Arch Underpass is located in western Lebanon, on Glen Road, a rural-industrial route paralleling the Mascoma River, which flows to its south.
Modern metal tie rods have been added to the arch, and the bridge is capped in concrete, which provides the foundation for the rail bed.
[2] The Northern Railroad was incorporated in 1844, and began service in 1848 between Concord, New Hampshire and White River Junction, Vermont.
