}} 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.〔(【引用サイトリンク】title=California Historical Landmarks in Nevada County )〕 The bridge was closed to traffic in 2010 and pedestrians in 2011 due to deferred maintenance and "structural problems".〔(Historic Bridgeport Bridge to close - Appeal-Democrat )〕 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.〔(State budget includes money to restore Bridgeport Covered Bridge - Transportation - The Sacramento Bee )〕 The Bridgeport Covered Bridge has the longest clear span of any surviving covered bridge in the world.〔〔The (Nevada County, California website ) that claims Bridgeport Covered Bridge has a longer span than the Old Blenheim Bridge had, also claims it is a National Historic Landmark. While the (National Historic Landmark search system ) does not report on the existence of this bridge as a National Historic Landmark. It is a California Historical Landmark and listed at the National Register of Historic Places.〕 ==Historic landmark== The bridge was listed in the National Register of Historic Places in 1971,〔 and it is also a California Registered Historical Landmark No. 390.〔 There are three plaques at the site. The inscription on the marker placed in 1964 reads:
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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bridgeport Covered Bridge」の詳細全文を読む スポンサード リンク
