Santa Cruz County, California Bridges: Soquel Avenue Bridge across the San Lorenzo River

December 2009 (36.97333-122.02278) Soquel Avenue Bridge
Continuing up the San Lorenzo River we arrived at the Soquel Avenue Bridge (36C0105), which is a 4-span, cast-in-place, reinforced concrete box girder bridge. This bridge is 380 ft long with a 112 ft long main span and a 60 ft wide deck supported on pier walls. It's just the latest in a series of bridges that were built at this location. 

The first recorded structure was a covered bridge built in 1874. In 1890 a timber trestle was added. These bridges were replaced in 1921 with a concrete and steel girder bridge. It was widened to four lanes in 1967 with a concrete precast I girder bridge on the north side. In 1982 severe flooding caused the collapse of the old southern side of the bridge. It was repaired with an I girder bridge in 1984. In 1999 the current bridge was built at this site.  It seems like the late 1990s was a time for Santa Cruz to do some flood control and refurbishing of bridges.
