Bay Bridge

Special Report: Sacramento Bee investigation of Bay Bridge

Since 2011, Sacramento Bee reporter Charles Piller has been digging into what happened during construction of the ​new $6.5 billion San Francisco Oakland Bay Bridge. The new span replaced the double-deck eastern section that failed during the 1989 Loma Prieta earthquake.

Piller's reporting has exposed a litany of errors in construction and oversight of the span by the California Department of Transportation, including ​hidden and suspect test results, shoddy construction practices, cracked welds, rusted tendons and broken anchor rods. The Bee's ongoing investigation has prompted multiple state inquiries, as well as introduction of legislation to reform Caltrans – including a new law that forces openness in how state experts review and approve megaprojects.
