The Toll Bridge Program Oversight Committee, or TBPOC, says it has a plan in place to fix broken bolts on the $6.4-billion San Francisco-Oakland Bay Bridge project. It was revealed in March that 32 of the 96 anchor bolt rods on the structure's eastern span broke when crews tightened them. The plan calls for the installation of custom-made steel saddles with hundreds of post-tension wires encased in concrete over two shear keys attached to the rods. TBPOC and main contractor American Bridge-Fluor Joint Venture say an equivalent amount of clamping force as the original bolt design's can be attained to hold down the shear keys.
