El Dorado County Bridges: Sciaroni Road Bridge across the North Fork of the Cosumnes River
The first bridge across the North Fork of the Cosumnes River is an single span steel girder structure with a timber deck. The girders are supported on end bents in front of metal retaining structures. The girders have rivets supporting a diaphragm near the support. The bridge was built in 1965.
The river is very shallow and clear at this location. The Sciaroni Bridge is 79 ft long, about 10 ft longer than the Sweeney Road Bridge and about 40 ft longer than the Happy Valley Road Bridge downstream. The river starts off flat and wide before cutting through a stone canyon as it travels west through El Dorado County.
