SAN RAFAEL (KPIX 5) – The CHP is investigating after another report of falling concrete hitting a vehicle on the Richmond-San Rafael Bridge.

Transportation officials say the bridge is safe, but many drivers aren’t buying it.

“I’m holding my breath every time I go over the bridge now, so I’m hoping they’ll figure out what’s going on and get it fixed,” driver Elyse Douglas said.

The CHP is investigating a female driver’s claim about concrete chunks falling on her windshield. She says it happened just before 8 p.m. Friday night while she drove on the lower deck towards Richmond. She told authorities that two pieces about the size of a baseball fell and caused damage to her car.

CHP officers stopped traffic on the lower deck after the report, but say they could not find any concrete debris.

A Caltrans spokeswoman dismissed the claim Saturday, saying engineers found a pothole mid-span, but nothing else.

As officers continue to investigate the claim, State Assemblyman Marc Levine says it’s time to replace the 63-year-old bridge.

“Instead of spending $900 million in maintenance, perhaps we should start doing the environmental work and the engineering work on a $3 billion replacement that will have fewer maintenance costs, but will also last for over 100 years rather than just another decade or two,” Levine said.
