Contra Costa County, California Bridges: Benicia Martinez Bridges across the Carquinez Strait

February 2014 (38.0415 Degrees, -122.12330 Degrees) Benicia Martinez Bridges

Some bridges that we recently viewed from Solano County make another appearance in Contra Costa County. The Benicia Martinez Bridges include a new segmentally constructed prestressed concrete box girder bridge that carries northbound I-680. Just behind it is the Southern Pacific Railroad Bridge composed of camelback Warren trusses, a lift span over the channel, and a deck truss approach. Behind the much lower railroad bridge is a tall deck truss bridge that carries southbound I-680.
