Golden Gate Bridge District Awarded $400M Federal Grant to Complete Seismic Retrofit

December 29, 2022 02:00 PM

The Federal Highway Administration (FHWA) announced today that the Golden Gate Bridge, Highway and Transportation District (District) has been awarded a $400M grant to complete the final phase of the Golden Gate Bridge seismic retrofit. The grant is provided through the FHWA’s Bridge Investment Program, which received $12.5 billion in funding from the Infrastructure Investment and Jobs Act of 2021.

"For more than eight decades, the Golden Gate Bridge has stood as a symbol of the innovative spirit of the Bay Area and our nation," Speaker Nancy Pelosi said.  "The Federal Highway Administration's $400 million investment will help ensure that this iconic landmark continues to safely and reliably serve our region for many years to come.  As a proud Representative of San Francisco, it was my privilege to work alongside President Biden, Secretary Buttigieg and the entire Bay Area Delegation to ensure our region receives its fair share of the Infrastructure Law's once-in-a-generation investment in America's bridges."

“The Golden Gate Bridge is an international icon and key transportation link for the Bay Area that serves tens of millions of residents and visitors every year,” said Denis Mulligan, District General Manager. “This vital funding allows us to finish strengthening the Bridge against disasters. Thanks to Speaker Pelosi, the Biden administration, and the entire Bay Area congressional delegation, the Golden Gate Bridge will be protected for generations to come.”

The Golden Gate Bridge seismic retrofit will strengthen the Bridge against major earthquakes and disasters. Due to the scale of the project, the seismic retrofit has been broken up into four phases, three of which have already been completed. The final phase of the project, called Phase 3B, includes strengthening the main span of the Bridge, two side spans, both towers, the south tower pier, and the underside of the toll plaza.

The construction budget is $879 million, with the remaining funding expected to come from a combination of state grants and District capital reserves. Construction is expected to begin in late 2024 and finish in 2029.

The first three phases of the seismic retrofit were completed between 2002 and 2014. With the earlier phases of the retrofit complete, the Bridge can safely withstand an earthquake over 7.0 in magnitude, but it may experience damage that requires closure after a major seismic event. Completion of the final phase of the retrofit will further harden the Bridge against damage from an earthquake or other disasters.

More information about the Golden Gate Bridge Seismic Retrofit is available on the project webpage.
