Tests on Bay Bridge Show No Failure

After dozens of seismic safety bolts on the new eastern span of the San Francisco-Oakland Bay Bridge broke, tests on remaining bolts have so far shown no sign of failure.
 
Toll Bridge Program Manager Tony Anziano told The Contra Costa Times that the 17-to-24-foot-long bolts made in 2010 are showing no signs of cracking, but tests are continuing.
 
Thirty-two of 96 bolts manufactured in 2008 broke earlier this year, putting the $6.4 billion bridge's scheduled Labor Day opening in doubt.
 
The long bolts, or rods, connect the bridge deck to so-called shear keys _ large shock absorbers that control movement during a temblor.
 
Officials on Wednesday are scheduled to update the public on a plan to fix the broken rods and whether the span will open on time.
