Built in 1883, it is a fine example of a king-post truss structure, and is one of the town's five 19th-century covered bridges.

[1] The Cilley Covered Bridge stands in a rural area about 1 mile (1.6 km) south of the central village of Tunbridge.

It carries Howe Lane, a side loop off Vermont Route 110, across the First Branch White River.

The bridge is set on abutments of stone, one of which has been faced in concrete, and is covered in vertical board siding and a metal roof.

The south side of the bridge has two square window holes, which improve visibility due to a sharp turn in the road at one end.
