Earthquake Engineering: The Golden Gate Bridge Is Preparing For ‘The Big One’

The B1M (April 26, 2023) – The Golden Gate Bridge in San Francisco is getting a huge earthquake upgrade.

IT’S the world’s most recognisable bridge and an icon of America. Defying incredible odds during its four years of construction, the Golden Gate has stood for over 80 years, and remains a critical piece of infrastructure — not just a pretty sight.

Today, it’s almost impossible to imagine San Francisco without this engineering marvel on its skyline. But that is now a very real possibility thanks to a threat that has loomed large over California for decades — a massive earthquake known as ‘The Big One’.

The iconic Golden Gate Bridge may not survive this unless it’s given some serious upgrades. Fortunately, that’s just what it’s getting with a huge seismic retrofit project that should see it stand for many more decades to come.

“It’s vitally important that we protect this icon, not just so people can come and take photos, but so our region can continue to function after a major seismic event,” Paolo Cosulich-Schwartz, director of public affairs for The Golden Gate Bridge, Highway and Transportation District, said.
