OAKLAND, Calif. (AP) — The planned repair for seismic safety rods that snapped on the new span of the San Francisco-Oakland Bay Bridge could cost between $5 million to $10 million, a state transportation official said on Wednesday.
California Transportation Commission Executive Director Andre Boutros told a meeting of the Bay Area Toll Authority on Wednesday morning the repair officials plan to go ahead with for the 32 rods that failed involves installing a saddle. Another repair option would have been more expensive.
He said officials are still hopeful they can open the bridge on schedule on Labor Day.
The rods connect steel earthquake safety devices called shear keys to the deck of the bridge and a large concrete cap. Shear keys would help control swaying during an earthquake.
The new bridge, which is replacing a span damaged during the 1989 Loma Prieta earthquake, is designed to withstand a major temblor. It is already years late in opening and billions of dollars over budget.
Documents released last month by the California Department of Transportation show its inspectors found structural integrity issues with some of the bolts several years ago, before they were installed.
The documents were unclear about whether the problems were remedied before the bolts were delivered and installed. The inspectors noted that the bolts failed elongation tests for structural integrity and said they were concerned about the quality of work by the company that galvanized the bolts to prevent corrosion.
