SACRAMENTO (CBS/AP) — Some cable sections and rods on the new San Francisco-Oakland Bay Bridge are rusting.
The Sacramento Bee reported Sunday that the findings have alarmed engineering experts who say the rust could have long-term implications for the new span.
The $6.5 billion bridge has an unusual design: A single cable comprised of 137 steel strands loops over a tower and under the bridge. That cable is secured inside chambers designed to keep out water and marine air to prevent corrosion.
The newspaper says rust has been found inside one of the chambers where the suspension cable is attached.
Engineering experts tell the newspaper the corrosion is significant because it makes the rods and the cable strands vulnerable to cracking.
Bridge spokesman Andrew Gordon says there is no concern about corrosion.
