SAN FRANCISCO — Caltrans engineers say they’re cautiously optimistic that they won’t have to replace hundreds of steel rods and bolts after dozens failed on the new San Francisco-Oakland Bay Bridge.
The San Francisco Chronicle says tests began this month on 700 steel rods and bolts on the eastern span that are considered at risk of cracking.
Samples are being dunked in saltwater and stretched to simulate bridge loads. Brian Maroney, Caltrans chief engineer for the span, says the rods have held up, and that could indicate they’re strong enough to do the job.
But he’s not drawing any conclusions until the tests are completed.
The tests were ordered after 32 seismic safety bolts broke in March, threatening to delay the Sept. 3 opening of the $6.4 billion span.
