CONTRA COSTA COUNTY — Due to unexpected rain over the past two nights in the Brentwood area, Caltrans Construction has unfortunately lost two days from the paving schedule. As a result, Caltrans has revised the schedule for the full closure needed for ongoing paving on State Route 4 (SR-4), spanning from Hillcrest Avenue to Byron Highway. The extended closure will now occur nightly between Balfour Road and Marsh Creek Road along SR-4, beginning May 31, 2026, through June 1, 2026, from 7:30 PM until 5:00 AM each night.
Full Closure of Marsh Creek Road (SR-4) is tentatively set to return Tuesday, June 1, 2026. Access during these times will be limited to local residents, business owners, and their employees. Please note: all scheduled work is weather dependent and may change.
