[1] The Simpsonville Bridge is located on Grafton Road (Vermont Route 35) about 2 miles (3.2 km) north of the village of Townshend, spanning Simpson Brook just east of the junction with Simpson Brook Road.

The bridge is built out of rough-cut and roughly-course granite blocks, now mortared with a variety of materials.

The bridge is topped by a gravel base and paved roadway, and has a total width of 35 feet (11 m), including the culvert extensions.

[2] This bridge is one of more than about 40 built in Towshend and other nearby communities by James Otis Follett, a local mason.

Follett's entire opus is distinctive, as it was produced at a time when most bridges were built with iron and steel.
