Retrofit and Renewal

A massive seismic retrofit program costing over $400 million reinforced the bridge’s ability to withstand a major earthquake on the nearby San Andreas Fault. The bridge district embraced new tolling technology, eliminating human toll collectors in favor of all-electronic collection. The 75th anniversary celebration in 2012 drew global attention and reaffirmed the bridge’s status as one of humanity’s greatest engineering achievements.
