Comments:
Closed. The bridge was constructed in 1862 to serve miners travelling from San Francisco and the Central Valley to gold mines in Nevada County, California. It replaced a bridge washed out by heavy rain. The Douglas fir structure was built by J.W. Woods, owner of a sawmill in the mountains. The siding of the 24-panel truss was constructed to accentuate the bridge's arch. The bridge remained in private ownership until 1901 when Nevada County assumed ownership and declared it a free and public highway. In 1918, when the state authorized the construction of the new state highway system, including Highway 49, use of the Bridge as a transportation corridor diminished; though it remained open as part of a local road. Nevada County constructed a new concrete bridge to bypass the covered bridge which was closed to traffic in 1972. Promotional materials often refer to it as the longest single span covered bridge in the world. After the loss of New York’s Blenheim Bridge in August 2011, it is now the longest single span covered bridge in the US. In 2014, the bridge was completely closed after an inspection revealed that due to decay and failure of some structural members, the bridge was unstable and required immediate stabilization to prevent imminent collapse. A suspension system supported by steel I-beam structures at each end. The bridge will undergo a restoration beginning in late 2018 which will remove the temporary suspension system.
