Over the next decade, the Golden Gate Bridge will undergo extensive construction to enhance its earthquake resilience. Although the bridge withstood the Loma Prieta earthquake, it remains vulnerable to damage from closer epicenter quakes. A significant retrofitting project has been in progress since 1990. The project aims to strengthen the bridge's towers and roadway, ensuring they can cope with seismic activity. Engineers note that certain bridge components may not move synchronously during an earthquake, potentially leading to serious misalignments and damage that could render the bridge inoperable for extended periods.
The Golden Gate Bridge is designed to withstand significant ground shaking, likely avoiding collapse even in strong quakes but could still suffer major damage from closer epicenters.
The retrofit project includes shoring up the viaducts and retrofitting the two 746-foot towers and 6,450 feet of main roadway to prevent severe damage from earthquakes.
