On May 21, 1927, the Carquinez Bridge was dedicated and marked the completion of the first direct highway link between the cities of Sacramento and San Francisco. Prior to the completion of the bridge, ferry service was used to transport vehicles across the Carquinez Strait, which had been in existence across the Carquinez Strait since the late 1840s.

Designed by the engineering firm of Robinson & Steinman, the Carquinez Bridge took 4 years and 8 million dollars to construct. Over 14,000 tons of steel was used for the 3,300 feet long bridge as it spanned the Carquinez Strait between the cities of Vallejo and Crockett. In 1958, due to increased traffic, a second bridge was built parallel to the 1927 bridge. Hailed for its engineering, this bridge was the second largest bridge in the United States when it was first built. The 1927 bridge was deemed seismically unsafe and was replaced in 2003.
