Richmond Bridge lanes reopen after concrete crashes onto lower span

All eastbound lanes of the Richmond-San Rafael Bridge have been reopened after two lanes were closed when pieces of concrete fell from the upper to lower span of the bridge, according to the California Highway Patrol.

The No. 3 and 4 lanes were closed for emergency roadwork after concrete was reported falling just west of the mid-span of the bridge around 12:45 p.m. A Sig-alert was issued around 2:10 p.m. Both lanes reopened at 3:40 p.m.

Bridge inspectors responded around 2:30 p.m., according to the CHP.

The bridge was temporarily closed on Feb. 7 after chunks of concrete fell onto the lower deck. Investigators determined an expansion joint that allows the bridge to expand or contract with rising or cooling temperatures had failed.
