The Southern Crossing is a proposed highway structure that would span San Francisco Bay in California, somewhere south of the San Francisco–Oakland Bay Bridge and north of the San Mateo–Hayward Bridge. Several proposals have been made since 1947, varying in design and specific location, but none of them have ever been implemented because of cost, environmental and other concerns.[1][2]
