The chief designer of the new, $6.4 billion eastern span of the San Francisco-Oakland Bay Bridge says more than 2,000 bolts and rods on the span do not need to be replaced.
The bolts and rods were called into question after 32 other bolts cracked when they were tightened last year.
But bridge designer Marwan Nader told bridge oversight officials at a meeting on Thursday that the other 2,200 bolts and rods on the span are likely to be more corrosion-resistant than the 32 that failed.
Although they will need extra protection against corrosion, Nader said they can remain in place.
A final decision about replacing at least some of the remaining bolts is still pending. But according to the San Francisco Chronicle (http://bit.ly/1o02lDa), Steve Heminger, chairman of the bridge oversight panel, said he was encouraged by Nader’s assessment.
