Caltrans will begin repaving the Richardson Bay Bridge in Marin Sept. 25 to help preserve the existing span and to decrease the probability of costly repairs in the future.

The construction work will involve the replacement of the existing asphalt concrete bridge deck surface with polyester concrete in both the northbound and southbound directions of the bridge. Lane closures will start near the Rodeo Avenue off-ramp and end right before the Seminary Drive off-ramp.

  • The two far-right lanes (No. 4 and 5 lanes) will be closed from 5 p.m. until 8 a.m.
  • The three left lanes (No. 1, 2 and 3) will remain open. 
  • Drivers should expect delays in the evening hours of Sept. 25 and use alternate routes like the San Rafael/Richmond Bridge and the Bay Bridge if possible.

The project will continue with grinding of the asphalt and placing of the polyester concrete on Monday, Sept. 26, through Friday, Sept. 30, from 8 p.m. until 8 a.m. each day, according to Caltrans. 

The bridge, completed in 1956, is about 3,000 feet long and is part of Highway 101.
