Caltrans has announced a lane closure and traffic shift tonight on westbound Interstate 580 leading to the Richmond-San Rafael Bridge.
The notice from the agency:
Interstate 580 Scofield Avenue and Western Drive Bridge Decks Replacement Project
Traffic Shift Planned for Eastbound Interstate 580
Contra Costa County – Tonight, September 30, Caltrans will close one lane of westbound Interstate 580 from 9 p.m. to 6 a.m., from Marine Street to the Richmond-San Rafael Bridge Toll Plaza. The eastbound on-ramp from Western Drive to Interstate 580 will also be closed from 8 p.m. to 5 a.m.
Tomorrow, October 1, Caltrans will close the far right lane at the Richmond-San Rafael Toll Plaza, from 6 a.m. to 4 p.m., from Castro Street to the Richmond-San Rafael Bridge Toll Plaza. This closure is necessary to build the foundation for a new overhead sign. Please be alert for construction workers during this lane closure.
On Wednesday night, October 2, Caltrans will shift traffic for eastbound Interstate 580 just east of the Richmond-San Rafael Bridge. Caltrans will close one eastbound lane from 7 p.m. to 6 a.m., and also close the eastbound on-ramp from Western Drive to Interstate 580, from 8 p.m. to 5 a.m.
Eastbound traffic will be moved to a split traffic configuration, with one left lane, one right lane, and construction taking place in an island between the lanes. With this lane configuration, it is imperative that drivers slow down and observe the construction speed limit of 45 MPH. The California Highway Patrol will be on site to enforce this speed limit and to maintain safety for motorists and construction workers.
In general, after the traffic shift, the eastbound Western Drive on-ramp will be closed Sunday night through Thursday night, from 8 p.m. to 5 a.m. The left eastbound lane will be closed on Sunday night from 10 p.m. to 6 a.m., and Monday through Thursday nights from 7 p.m. to 6 a.m.
This is an active construction site and the 45 MPH speed zone will be enforced by the California Highway Patrol. Drive cautiously through the construction zone and leave a safe traveling distance between your vehicle and the vehicle ahead of you. Please remember to “Slow for the Cone Zone.”
