Midnight to 6:00 am for Mokelumne Trail overcrossing

BRENTWOOD, CA – In partnership with the City of Brentwood, the Contra Costa Transportation Authority (CCTA) is constructing the Mokelumne Trail Bicycle and Pedestrian Overcrossing to provide safe access to cyclists and pedestrians for commuting and recreational travel, reconnecting two sides of the trail that were separated by the expansion of State Route 4.  The overnight closure will facilitate final adjustments to the falsework as part of the construction work installing the pedestrian and bicyclist crossing over State Route 4.  This closure will impact State Route 4 in both the Eastbound and Westbound directions.  CCTA and the California Department of Transportation (Caltrans) have scheduled the closure during the early morning hours in order to minimize impacts to the motoring public.

Overnight Freeway Closure of State Route 4 between Lone Tree Way and Sand Creek Road
In order to ensure crew and public safety during the planned construction work, a temporary nighttime freeway closure in both directions of State Route 4 will occur between Friday, May 5, 2023 and Saturday, May 6, 2023 on the following schedule (weather permitting):
Eastbound and Westbound Highway 4 will be closed from midnight on Friday, May 5 until 6:00am on Saturday, May 6, 2023. 

Detours
Detours will be in place to reroute drivers around the closure and are planned as follows:
Eastbound traffic will be directed to exit at Lone Tree Way, go eastbound to Shady Willow Lane, then southbound on Shady Willow Lane to Sand Creek Road, before proceeding 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 will be needed over the course of the next eight weeks (weather dependent) to facilitate concrete pours for the stem and soffit and deck of the future Mokelumne Trail Bicycle and Pedestrian Overcrossing.  Additional information regarding dates and detours will be provided once the schedule is confirmed.  This project is anticipated to be complete in late summer or early fall of 2023.
