Quinlan's Covered Bridge is located in a rural area of southeastern Charlotte, which provides access for Monkton Road (Town Highway 36) over the Lewis Creek to an adjacent intersection with Spear Street (a major Class 2 Town Highway) at the bridge's western end.

Each truss has, in addition to diagonal braces and vertical posts, a pair of timber arches bolted to it.

It has a gabled roof, and its exterior is clad in vertical board siding, which extends around to the inside of the portals.

This is common in Vermont where multiple bridges crossed the same body of water in the same town.

The name "Sherman" comes from the owner of a sawmill that was located adjacent to the bridge site.
