[1] The Mill Covered Bridge is located on the north side of Tunbridge village, where it carries Spring Road across the First Branch White River, west of Vermont Route 110.

It is a single-span structure, with multiple kingpost trusses resting on abutments of stone and concrete.

The exterior consists of a metal roof and vertical board siding, the latter extending around the portals and a short way into the interior.

The floor consists of planking laid parallel to the trusses on supporting stringers.

[2] This bridge was severely damaged by ice floes in March 1999 and subsequently demolished.
