Temporary Changes to I-5 Overnight Work Schedules and Freeway Lane Closures

ENCINITAS – Due to reduced traffic volumes along Interstate 5 (I-5), the Caltrans and SANDAG Build NCC construction team are making changes to overnight freeway work schedules to further advance construction progress.

  • Starting the week of April 19, overnight highway construction crews will begin working Monday through Friday nights, as opposed to the standard Sunday through Thursday night schedule.
  • Starting Monday, April 20, temporary lane closures along I-5 will begin each night at 7:30 p.m., as opposed to the standard 9 p.m. start time. All temporary lane closures will continue to be lifted at 5 a.m. the following morning.

During construction, nearby residents and businesses may experience noise and lights, including Occupational Safety and Health Administration (OSHA) required vehicle back-up alarms. Crews will work to minimize noise and impacts to all nearby communities.

To ensure safety for both motorists and the construction crews through this work, drivers are reminded to “Drive 55 on the 5” in the Build NCC construction zone and that traffic fines are doubled in construction zones. The SANDAG operated Motorist Aid service for roadside assistance can be easily accessed by dialing 5-1-1 anywhere in San Diego County. Additionally, the “Move Over” law requires all drivers to move over a lane or, if they are unable to do that safely, slow down when they see amber flashing lights on Caltrans vehicles, law enforcement and emergency vehicles, and tow trucks.
