The 1870s Williamsville Covered Bridge is a historic covered bridge, carrying Dover Road over the Rock River in Newfane, Windham County, Vermont. Probably built in the 1870s, this Town lattice truss bridge is probably the oldest covered bridge in Windham County.

The Williamsville Bridge is the last of the seven covered bridges that once graced Newfane's countryside. It carries Dover Road, the main road leading west from the village, across the Rock River, whose valley the road follows in this area. The bridge has a length of 118 feet and a width of 21 feet, allowing for a single travel lane. It has a portal clearance of 11 feet, and its roof is metal. It is supported by two Town lattice trusses, and its exterior is clad in vertical board siding. Its original wooden roadway supports have been replaced by steel beams, and the roadbed is paved.

The bridge built in the 1870s by Eugene P. Wheeler is the last surviving historic covered bridge in the town.

State bridge inspectors determined that the Williamsville Covered Bridge should no longer be asked to support emergency vehicles. After years of discussion as to whether to replace the bridge with a modern concrete and steel span, or reconstruct the ancient bridge again, the town accepted the state's proposal to replace it with a replica capable of carrying modern traffic.

Construction of the new bridge began in late November 2009. The old bridge was taken down in July 2010, and the new bridge was placed over the river on August 2, 2010.

Of the over 500 covered bridges that were built in the state of Vermont, as of 2019, only 104 remain.

Length of largest span: 95.1 ft.
Total length: 117.1 ft.
Deck width: 17.1 ft.
Vertical clearance above deck: 11.7 ft.
