During the 1989 Loma Prieta earthquake, a section of the eastern span's upper deck collapsed onto the lower deck and the bridge was closed for a month. After this episode, it was decided to replace the east span with a more modern,
earthquake-resistant span. Construction on the new span was started in 2002 and was completed in 2013. The older cantilever bridge will eventually be torn down.
This new suspension bridge is a self-anchored suspension bridge. As of April 15, 2011, the single-towered self-anchored suspension span (SAS) tower was structurally complete. Its crowning main cable saddle was placed on May 19 and the final tower head, was lifted and fitted later in 2011. The installation of the eastern deviation saddles and strand anchor points followed by main cable spinning and suspender cable placement. Much of the construction was made possible by the Left Coast Lifter, a 25-story floating crane.
Separated and protected bicycle lanes are a visually prominent feature on the south side of the new east span. The bikeway will carry recreational and commuter cyclists between Oakland and Yerba Buena Island. Eventually a park and recreational area are planned for the area around the east landing.
As of the 2011 season, the new eastern span is featured in the Golden State Warriors logo.
