The San Francisco Bay Bridge opened on November 12, 1936, six months before the Golden Gate Bridge. Designed by Charles H. Purcell, and built by American Bridge Company, it originally carried automobile traffic on its upper deck, and trucks and commuter trains on the lower, but after the Key System abandoned rail service, the lower deck was converted to all-road traffic as well.

During the 1989 Loma Prieta earthquake, a portion of the eastern section's upper deck collapsed onto the lower deck and the bridge was closed for a month.

On March 5, 2013, a public art installation called The Bay Lights was activated on the western span's vertical cables. The installation was designed by artist Leo Villareal to commemorate the 75th anniversary of its opening. and consists of 25,000 LED lights.
