Bridgeport Covered Bridge, Covered bridge in Nevada County, California, United States

Bridgeport Covered Bridge spans the South Yuba River in Nevada County, California. Built in 1862 by David John Wood with lumber from his mill in Sierra County, it has a gabled shingled roof and reddish-brown shingled side walls. The left entrance is timber-framed with a triangular gable above a rectangular opening, and the bridge rests on a mortared gray stone abutment.

Built in 1862 by David John Wood, the bridge provided a critical crossing during the Comstock Lode mining boom when transporting goods and people between San Francisco Bay and Virginia City. It became a key link in the transportation network that supported the surrounding mining operations.

The name comes from the Bridgeport settlement beside the South Yuba River crossing. The 1964 State Historical Landmark plaque, rededicated in 2014, records that the bridge was part of the Virginia Turnpike Company toll road serving the northern mines and the Nevada Comstock Lode, and that an associated ranch offered rest and repair to travellers. Four plaques now stand at the site.

The bridge reopened to pedestrians in November 2021 after a restoration funded by $1.3 million in state budget legislation signed in 2014. It stands southwest of French Corral and north of Lake Wildwood, reached from either end of the crossing. Four plaques at the site mark its landmark status.

The bridge holds the world record for the longest unsupported single span of any existing wooden covered bridge, with a span between supports exceeding 60 meters. This exceptional engineering achievement was made possible by the Howe truss design that distributes load evenly across the entire length.
