"Starting next week, motorists will encounter single and multiple lane closures during night hours in both directions of Interstate 5 near DuPont as crews begin a project to replace over 4.5 miles of concrete median barrier.
Crews will close a single lane of northbound and southbound I-5 between 8 p.m. and 6 a.m. on Tuesday and Wednesday, Sept. 4-5, to install construction signs. Barrier work, and multiple night lane closures, will begin the following week. From 8 p.m. to 6 a.m. Monday, Sept. 10 through Friday, Sept. 14, crews will close multiple lanes of southbound and northbound I-5 starting near Berkeley Ave.
The closures will be repeated in both directions of I-5 in various locations within the project limits through mid-October."
