When I-205 opened in December 1970, it replaced 11th Street, which passed through downtown Tracy, as part of the primary all-land connection between the Bay Area and Sacramento until the Carquinez Bridge opened in 1927 and carried the Lincoln Highway and later US Route 50 (US 50). 11th Street is now signed as I-205 Business (I-205 Bus.).
