Caltrans will conduct overnight pavement work on the 405 Freeway in the Sepulveda Pass from Monday, Oct. 26, to Friday, Oct. 30, 2026. Los Angeles commuters should prepare for lane and ramp closures between 9 p.m. and 6 a.m. nightly.
Why it matters
This $143.7 million pavement rehabilitation project aims to improve long-term safety and freeway mobility. Local residents and drivers should anticipate significant overnight traffic shifts, reduced speed limits, and construction noise.
The work involves multiple lane closures between Van Nuys and Westwood, with speed limits reduced to 55 mph through the construction zone. These measures facilitate K-rail installation and paving between 9 p.m. and 6 a.m.
The players
Caltrans
The California Department of Transportation responsible for the planning and maintenance of the state's highway system.
The details
Crews are performing pavement rehabilitation to extend the lifespan of the freeway surface within the Sepulveda Pass. The process involves installing protective K-rails and applying new pavement materials while lanes are temporarily taken out of service. Drivers should expect noise, vibrations, and dust near the construction zones as work progresses through the night.
Timeline
Monday, Oct. 26, 2026, to Friday, Oct. 30, 2026, from 9 p.m. to 6 a.m.
The Home Front
This project aligns with the ongoing regional effort to preserve aging infrastructure through extensive pavement rehabilitation. It follows a pattern of large-scale maintenance work designed to maintain safety standards across major commuter corridors.
If you live near the Sepulveda Pass, prepare for increased overnight noise and vibrations throughout the week. Check your planned commute routes in advance to navigate around the various ramp and lane closures scheduled nightly.
The takeaway
Drivers should build extra time into their travel plans for the week of Oct. 26 due to the 55 mph speed limit reduction. Please remain alert for construction workers and equipment while navigating the Sepulveda Pass at night.
