Golden Gate Bridge

Client: Golden Gate Bridge Highway and Transportation District
Location: San Francisco, CA
Start Date: June 1997
End Date: February 2002
Final Contract Amount: $59.6 million

Balfour Beatty Infrastructure, Inc. helped to improve the Golden Gate Bridge's vulnerability to earthquakes by performing a seismic retrofit. Five independent truss spans were strengthened by connecting them together so they can move together as one unit. Four steel support towers were replaced one-by-one and new foundations were constructed for each.

During the five-year project, which began in 1997, Balfour Beatty Infrastructure employees encountered an endangered species - the Mission Blue Butterfly. All necessary precautions were taken to protect the Mission Blue Butterfly and its habitat so that construction work would not bring harm to this rare and beautiful creature while we successfully completed the project.

Balfour Beatty Infrastructure was pleased to have participated in preserving and strengthening the structural integrity of this international icon.
