The 1883 Cilley Covered Bridge is a historic 19th-century covered bridge in a rural area about 1 mile south of the central village of Tunbridge in Orange County. It carries Howe Lane, a side loop off Vermont Route 110, across the First Branch White River. It is a single-span Kingspost truss structure, 66 feet long and 19 feet wide, with a roadbed 16 feet wide (one lane). 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. The trusses are set at a skew, giving the bridge the shape of a parallelogram. The portals are square, and the exterior sheathing extends around to the ends of the trusses on the interior.

The bridge was built by Arthur C. Adams in 1883 and has been little altered since then. It is one of six bridges in a 7-mile stretch of the First Branch White River, representing one of the highest concentrations of covered bridges in the state. Located in Orange County, Vermont, and was rehabilitated in 2006.

The Bridge is also known as Lower Covered Bridge and First Branch White River Bridge.
