San Francisco-Oakland Bay Bridge East Span Replacement

The San Francisco-Oakland Bay Bridge crosses the entirety of the famed California bay and is made up of two segments – the west span and the east span. Carrying approximately 270,000 vehicles a day, it provides a critical connection for the region and the commuters traveling along Interstate 80.

When Caltrans District 4 determined that the east span of the bridge, which connects the shores of Oakland to Yerba Buena Island, was in need of replacement, HNTB provided program management and project control services to ensure the new span’s successful delivery.

In addition to the Bay Bridge replacement, HNTB also served Caltrans and their partner, Bay Area Toll Authority, in a supporting role on individual projects within its broader infrastructure program. This included the seismic retrofit design and construction coordination of the Bridge Yard building, a historic facility that was once used for the maintenance of trains that once traveled over the Bay Bridge. HNTB provided preliminary work for Gateway Park, now known as Judge John Sutter Regional Shoreline, a park located at the Oakland shoreline of the Bay Bridge.

Upon its completion and opening in 2013, the Self-Anchored Suspension portion of the San Francisco-Oakland East Span Bay Bridge was named the world’s longest self-anchored suspension bridge. The east span includes a multi-use path where pedestrians and bicyclists can now enjoy a trip out to the island from the Oakland shoreline. Today, it stands as a testament to project collaboration and continues to serve as a vital link to I-80 travelers in the San Francisco Bay Area.
