Closures scheduled for Sunday night include:
— Up to two lanes in each direction from 8 p.m. to 6 a.m.;
— The northbound Lake Hughes Road on- and off-ramps from 5 p.m. to 6 a.m.;

Closures scheduled from Monday through Thursday nights include:

“These closures are necessary to perform slab replacement, upgrade guardrails and repave the freeway,” according to a Caltrans statement. “Once completed, the project will improve ride quality and enhance worker safety.”
Nearby residents and businesses may experience noise, vibrations and grinding during construction, Caltrans said.
Construction began in spring 2025 and is scheduled to continue through winter 2026-27. Real-time updates are available on Caltrans QuickMap.
