San Francisco-Oakland Bay Bridge East Span Replacement

๐Ÿ‡บ๐Ÿ‡ธ San Francisco, CA

When the magnitude 6.9 Loma Prieta earthquake hit on October 17, 1989, a 50-foot section of San Francisco Bay Bridge collapsed onto the deck below.

Almost a decade later, when a design concept was approved, Caltrans selected Moffatt & Nichol in a joint venture to design the new San Francisco-Oakland Bay Bridge East Span. Our team provided full range of design, program management, construction support, and engineer-of-record services. Seismic design improvements made after the Loma Prieta earthquake led to the extensive seismic retrofit of California bridges. Moffatt & Nichol participated in the development of design criteria.
