It is a masonry arch bridge, carrying U.S. Route 7 (US 7) across Sugar Hollow Brook a short way east of the town center.
Built in 1899, it is one of a modest number of surviving masonry arch bridges in the state, and exhibits particularly high quality period workmanship.
[1] The Colburn Bridge is located about 0.5 miles (0.80 km) east of the town center of Pittsford, on US 7, the major north–south route in western Vermont.
In their place are modern metal guardrails, partly set on concrete slabs that cantilever out slightly from the masonry structure.
At the time of its listing on the National Register of Historic Places in 1990, it was one of seventeen documented masonry arch bridges in the state.
