[1] The Martin's Mill Covered Bridge is located about 0.6 miles (0.97 km) east of United States Route 5 on Martinsville Road in a rural wooded area of southern Hartland, with the highway bridges of Interstate 91 rising just to its east.

The bridge is a single span Town lattice truss, resting on concrete abutments.

The exterior of the bridge is clad in vertical board siding, which wraps around for a short distance on the insides of the portals.
