A heads up to motorists who use Interstate 580 and the Richmond-San Rafael Bridge. Caltrans will shift lanes again for its ongoing Interstate 580 Scofield Avenue and Western Drive Bridge Decks Replacement Project.
The agency issued the following announcement Wednesday:

Traffic Shift Planned for Eastbound Interstate 580

Contra Costa County – Tomorrow, September 26, and Friday, September 27, from 6 a.m. to 6 p.m., Caltrans will close the far right lane of three lanes of westbound Interstate 580 just east of the Richmond-San Rafael Toll Plaza. This closure is necessary in order to build the foundation for a new overhead sign. Cash lane drivers will merge left to the center lane, since the far right lane will be closed. Please be alert for construction workers during this lane closure.

Ongoing Construction
On Wednesday night, October 2, Caltrans will shift traffic for eastbound Interstate 580 just east of the Richmond-San Rafael Bridge. 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 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. The eastbound Western Drive on-ramp will be closed Sunday night through Thursday night, from 8 p.m. to 5 a.m. Detour: during eastbound Western Drive ramp closures, motorists will travel westbound across the Richmond-San Rafael bridge, exit at San Quentin, cross under the freeway and take the eastbound I-580 on-ramp.

Note: this ramp closure will not affect motorists traveling through the construction zone from Contra Costa County westbound across the Richmond-San Rafael Bridge, or motorists travelling eastbound from Marin County.

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.”
