From 12:01 a.m. to 5 a.m. Sunday, Caltrans will close left lanes for nearly a mile on westbound Highway 24 near the Caldecott Tunnel in Orinda. The tunnel's third bore and westbound Highway 24 in Oakland from the tunnel to the northbound state Highway 13 connector will also be closed, according to Caltrans.
Crews will work overnight to remove an old, 80-foot-wide directional sign that has been replaced by new signs, Caltrans officials said.
Eastbound traffic on Highway 24 will remain open to traffic during the closures.
