About Carquinez Bridge

  • Body Of Water Spanned: Carquinez Strait
  • Bridge Type: Suspension bridge
  • Locale: Crockett

The Carquinez Bridge refers to parallel bridges spanning the Carquinez Strait, forming part of Interstate 80 between Crockett and Vallejo, California. The name originally referred to a single cantilever bridge built in 1927, helping to form a direct route between San Francisco and Sacramento. A second parallel cantilever bridge was completed in 1958 to deal with the increased traffic. Later, seismic problems of the 1927 span led to the construction and 2003 opening of a replacement: a suspension bridge officially called the Alfred Zampa Memorial Bridge. Currently, the Alfred Zampa Memorial Bridge carries westbound traffic from Vallejo to Crockett, and the 1958 cantilever span carries eastbound traffic. Toll is only charged to eastbound traffic. The original bridge, a steel cantilever bridge, was designed by Robinson & Steinman and dedicated on May 21, 1927. It cost $8 million to build and was the first major bridge in the San Francisco Bay Area. Upon completion of the 1927 bridge, the Lincoln Highway was rerouted over the span. Its original alignment from Sacramento to San Francisco avoided the un-bridged waterways of the San Francisco Bay and the Sacramento Delta by routing itself
