San Francisco–Oakland Bay Bridge

The San Francisco-Oakland Bay Bridge extends 7200 meters across San Francisco Bay with steel spans connecting San Francisco to Oakland through Yerba Buena Island.

The bridge opened on November 12, 1936, after three years of construction, becoming the longest bridge structure in the world at that time.

The Bay Bridge features an installation of 25,000 LED lights that transform the western span into a nighttime light display visible throughout the bay area.

The bridge carries more than 240,000 vehicles daily across its ten traffic lanes, with electronic toll collection systems managing the westbound traffic flow.

The structure combines both suspension and cantilever bridge technologies, with a tunnel running through Yerba Buena Island to connect its eastern and western sections.
