SAN FRANCISCO (AP) — Officials in charge of building a new eastern span of the San Francisco-Oakland Bay Bridge repeatedly questioned the work and quality control of companies involved in making long seismic safety bolts that broke while being tightened.
In March, a third of the 96 bolts failed, and transportation officials said it could take months to find the cause and fix the problem, meaning the scheduled Labor Day opening of the new, $6.3 billion span could be in jeopardy.
