OAKLAND (CBS/AP/BCN) — Officials are studying a temporary fix for cracked seismic safety bolts on the San Francisco-Oakland Bay Bridge that could allow the new eastern span to open as scheduled on Labor Day after all, but they said Wednesday a decision had not yet been made on the work.
At this point, members of the Toll Bridge Program Oversight Committee said, the longer-term repairs were still scheduled to be finished by Dec. 10.
A bridge engineering expert surprised the transportation officials who are overseeing the $6.4 billion project with his comments at Wednesday’s committee meeting about a short-term fix that could avoid derailing the planned opening of the span.
Frieder Seible recommended a “shimming” idea — installing steel plates into the area of the broken bolts to help prevent movement during an earthquake on the new span, which is aimed at being safer during a quake than the existing span built 77 years ago.
The temporary fix would be in place while long-term repairs occurred, said Sieble who is an emeritus dean at the University of California at San Diego and also chairs the Toll Bridge Program Seismic Safety Peer Review Panel.Comments (2)
