The Bridgeport Covered Bridge is located in Bridgeport, Nevada County, California, southwest of French Corral and north of Lake Wildwood. It is used as a pedestrian crossing over the South Yuba River. The bridge was designed by David Ingefield Wood, and built in 1862. Its lumber came from Plum Valley in Sierra County, California.[5] The bridge was closed to traffic in 2010 and pedestrians in 2011 due to deferred maintenance and "structural problems".[6]

The Bridgeport Covered Bridge has the longest clear span of any surviving covered bridge in the world.[1][7]

Historic landmark[edit]

The bridge was listed in the National Register of Historic Places in 1971,[4] and it is also a California Registered Historical Landmark No. 390.[3] There are three plaques at the site.

The inscription on the marker placed in 1964 reads:

"Built in 1862 by David Isaac John Wood with lumber from his mill in Sierra County, this bridge was part of the Virginia Turnpike Company toll road which served the northern mines and the busy Nevada Comstock Lode. Utilizing a combination truss and arch construction, it is one of the oldest housed spans in the west and the longest single-span wood-covered bridge in the United States."[8]

Longest span[edit]

A report by the U.S. Department of the Interior states that the Bridgeport Covered Bridge (HAER No. CA-41) has clear spans of 210 feet (64 m) on one side and 208 feet (63 m) on the other, while Old Blenheim Bridge (HAER No. NY-331) had a documented clear span of 210 feet (64 m) in the middle (1936 HABS drawings).[9]

With the 2011 destruction of the Old Blenheim Bridge, the Bridgeport Covered Bridge is the undisputed longest-span wooden covered bridge still surviving. Historically, the longest single-span covered bridge on record was Pennsylvania's McCall's Ferry Bridge with a claimed clear span of 360 feet (110 m) (built 1814–15, destroyed by ice jam 1817).[9]
