Lefty O'Doul Bridge

Lefty O'Doul Bridge is a bascule bridge crossing Mission Creek Channel in San Francisco with five traffic lanes. The structure includes two northbound lanes, two southbound lanes, and one reversible center lane that shifts direction based on traffic flow.

Joseph Strauss, who designed the Golden Gate Bridge, created this steel structure that opened on May 12, 1933 with Mayor Angelo Rossi in attendance. The project marked an important development in San Francisco's infrastructure at that time.

The bridge took its current name in 1980 to honor a baseball manager who coached the San Francisco Seals and promoted baseball in Japan. This naming reflects the area's deep connection to sports and international cultural exchange.

During events at Oracle Park stadium, the two easternmost lanes close to vehicle traffic and convert into pedestrian walkways. This arrangement improves access for fans attending games and reduces congestion in the surrounding area.

The structure incorporates concrete counterweights and timber fenders on both sides of the channel for stability. Two original harbor master cottages still stand on the piers, offering a glimpse into the area's working waterfront past.
