Interstate 580 Scofield Avenue and Western Drive  

Bridge Decks Replacement Project

Eastbound Lane  and Ramp Closures Continue

Contra Costa County – Eastbound lane and ramp closures continue for the Interstate 580 construction project east of the Richmond-San Rafael Bridge.

·      Tonight, Friday, October 11th, Caltrans will close one eastbound lane from 8 p.m. to 8 a.m.
·      The eastbound on-ramp from Western Drive to Interstate 580 will also be closed from 8 p.m. to 5 a.m.

Eastbound traffic is in a split traffic configuration, with one left lane, one right lane, and construction taking place in an island between the lanes. Due to this lane configuration, during construction, the left eastbound lane and eastbound Western Drive on-ramp will be closed to allow for staging of equipment, materials, and workers.  Those closures are essential for the safety of construction workers and the travelling public.

Closures for one eastbound lane and the eastbound Western Drive on-ramp will continue next week according to the following schedule:

·      Eastbound I-580 lane: Monday through Thursday night, from 8 p.m. to 6 a.m.
·      Eastbound Western Drive on-ramp: Monday through Thursday, from 8 p.m. to 5 a.m.

Caltrans has observed that during the day, some drivers are confused about the eastbound lane configuration. Please be aware that when both lanes are open, either lane will take motorists through the construction zone. They will remain on eastbound I-580. Due to narrower lanes and concrete barriers on both sides of the lane, drivers are slowing down in the construction site. Please allow at least 20 additional minutes during the eastbound afternoon commute.

This current lane configuration will continue until the end of October.  Then Caltrans will shift lanes to the left to allow the contractor to work on the right side of the eastbound bridge deck.  The project is scheduled to be completed in December.

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.”
