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 slabs of concrete similarly 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. 

Caltrans issued the following statement: 

"Minor spalling occurred on the upper deck of the Richmond-San Rafael Bridge this afternoon. Both lanes remain open on the upper deck and all lanes are now open on the lower deck while Caltrans crews perform inspections. The bridge remains safe and open to the public. Caltrans will provide additional information as available."
