Highway 4 closed in both directions Friday night and Saturday morning
CONTRA COSTA COUNTY, CA (June 16, 2023) — Overnight construction along the Highway 4 freeway will close traffic in both directions tonight.
In partnership with the City of Brentwood, the Contra Costa Transportation Authority (CCTA) is constructing the Mokelumne Trail Bicycle and Pedestrian Overcrossing. The project will provide safe access to cyclists and pedestrians for commuting and recreational travel. It also reconnects two sides of the trail previously separated by the expansion of State Route 4.
The overnight closure will enable the contractor to facilitate installation of the bridge deck for the pedestrian and bicycle crossing. This closure will impact State Route 4 in both the Eastbound and Westbound directions. CCTA and the Caltrans have scheduled the closure during the evening and early morning hours in order to minimize impacts to the motoring public.
The closure falls between Lone Tree Way and Sand Creek Road.
The freeway will close starting Friday, June 16, 2023, at 9 pm. Eastbound and Westbound Highway 4 remain closed until 6 am on Saturday.
Detours
Workers will place detours to reroute drivers around the closure.
Eastbound traffic exit at Lone Tree Way. It will continue eastbound to Shady Willow Lane, then southbound on Shady Willow Lane to Sand Creek Road. Finally traffic will proceed westbound on Sand Creek Road to the eastbound State Route 4 on-ramp.
Westbound drivers having to detour will exit on Sand Creek Road and go eastbound on Sand Creek Road to Shady Willow Lane, then northbound on Shady Willow Lane to Lone Tree Way, and proceed westbound on Lone Tree Way to the westbound State Route 4 on-ramp.
Future Freeway Closures
Additional overnight closures may be needed over the course of the summer to aid construction of the future Mokelumne Trail Bicycle and Pedestrian Overcrossing. Additional information regarding dates and detours will be provided as scheduled. This project is anticipated to be complete in late summer or early fall of 2023.
