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]

On June 20, 2014, California Gov. Jerry Brown signed budget legislation that included $1.3 million for the bridge's restoration. The work is slated to be done in two phases -- near-term stabilization followed by restoration. Restoration may not begin until 2018.[7]

The Bridgeport Covered Bridge has the longest clear span of any surviving covered bridge in the world.[1][8]

Historic landmark

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."[9]

The bridge was an important link in a freight-hauling route that stretched from the San Francisco Bay to Virginia City, Nevada and points beyond after the discovery of the Comstock Lode in 1859 sparked a mining boom in Nevada. Steamboats carried freight from the San Francisco Bay up the Sacramento River to Marysville, where it was loaded onto wagons for the trip across the Sierra Nevada via the Virginia Turnpike, and Henness Pass Road. The route across the bridge was ultimately eclipsed by the completion of the First Transcontinental Railroad as far as Reno in 1868 via Donner Pass, but it continued to serve nearby communities in the foothills until improved roads and bridges on other routes drew away most of the traffic.

Longest span

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).[10]

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).[10]
