Interstate 580 Scofield Avenue and Western Drive  
Bridge Decks Replacement Project
Maximum Speed Limit Reduced to 45 MPH
Lane Closures Continue

Contra Costa County – Construction continues for the Interstate 580 Scofield Avenue and Western Drive Bridge Decks Replacement Project. Lane closures are scheduled for westbound and eastbound Interstate 580, in the vicinity of the Richmond-San Rafael Bridge Toll Plaza. At least one lane in each direction will remain open at all times. Drivers should expect delays and allow extra time in their daily commute.

·        The speed limit was reduced to 45 MPH. The speed limit will be enforced by the California Highway Patrol.

·        In general, at night, due to construction activities, lanes will be reduced to one lane. If you are travelling on eastbound I-580, week night closures begin at 7 p.m. If you are travelling westbound, week night closures begin at 9 p.m.

·        In early May there will be structural work as well as roadway excavation as Caltrans begins to build the crossover in the median.

·        The long term, 90-day closure of the eastbound Western Drive on-ramp is expected to begin in June 2013.  There will be brief closures prior to that date when the contractor is working in the area.  However, when possible a flagger will allow vehicles through the work area.
