The base of the San Francisco/Oakland Bay Bridge has taken on some water in recent months, and judging by the latest reports it is saltwater and not rainwater.
The fear is that the water will corrode the high-strength steel rods that protect the 525-foot bridge tower against jostling around during earthquakes.
According to a report by the San Francisco Chronicle, water has been flooding the base of the rods for a while, but inspectors only recently determined that at least some of it is saltwater from the bay.
A report published in February insisted that the infiltration was rainwater.
Officials with the California Department of Transportation, Caltrans, are saying that any conclusions about infiltration or corrosion would be speculative until more inspections can be conducted.
The East Span of the bridge opened to traffic in September 2013 to phase out and replace the original span.
