It was built in 1892 by contractor G.H. McKay for Santa Cruz County on Glen Canyon Road and moved about half a mile upstream in 1939.","why_significant":"The nomination argues the bridge is significant for engineering and transportation as a typical Howe truss covered bridge. It is one of three surviving covered bridges in Santa Cruz County and is believed to be the southernmost covered bridge in California. It is also thought to be the first covered bridge in northern California moved as part of a community preservation effort.","narrative":"Spanning Branciforte Creek in DeLaveaga Park, this 83-foot wooden covered bridge was built in 1892 by contractor G.H. McKay on Glen Canyon Road to serve growing settlement north of Santa Cruz. Made of native redwood and Douglas fir, it uses a Howe truss, a simple modular design common in timber bridges across the country. The county condemned it in May 1939 because increased traffic called for a wider span. Local preservationists, volunteers and the WPA lifted it onto rollers and carts and moved it roughly half a mile upstream into the park, where it was rededicated in 1940. It is one of three covered bridges left in Santa Cruz County, and the nomination describes it as the southernmost in California and an early example of a community effort to save such a structure. The roof has been replaced, much of the siding has been lost, and a 1981 flood washed out its earlier foundation. Restoration plans are described but awaited funding.","period_of_significance":"1800-1899","architect_builder":"G.H.
