Faulty Bay Bridge bolts flagged years before shoddy work

Documents released by the California Department of Transportation show the company that made the faulty bolts for the Bay Bridge was flagged years before for shoddy work.

Several of the anchor bolts on the new eastern span snapped recently when workers tightened them.

The documents show that in 2007, a year before the bolts were delivered and installed, Caltrans gave Ohio-based Dyson Corporation a failing grade.

Caltrans wrote the company had big problems in its heat treatment area, a process that likely led to bolts snapping because they were too brittle.

Bridge authorities met this week to find a solution to the bolt problem. And now it's uncertain if the new eastern span will open by Labor Day as originally scheduled.
