Caltrans will implement nightly closures along the 405 Freeway through the Sepulveda Pass beginning October 13, 2026, as part of a $143.7 million pavement rehabilitation project. The work will impact transit between Westwood and Van Nuys through October 17.

Why it matters

This infrastructure work is designed to improve long-term freeway safety and extend the lifespan of the roadway pavement. Residents should anticipate significant traffic adjustments and noise during the overnight construction window.

The project represents a $143.7 million investment in the regional transit network. Closures are scheduled nightly between 9 p.m. and 6 a.m., with speed limits reduced to 55 mph in active construction zones.

The players

Caltrans

The California Department of Transportation is the state agency responsible for the design, construction, and maintenance of the state's highway and freeway system.

The details

Crews will conduct K-rail installation and paving operations that require lane and ramp restrictions across the Sepulveda Pass. This includes the closure of two northbound lanes between Sepulveda and Victory Boulevards, one northbound lane between Wilshire Boulevard and Skirball Center Drive, and three southbound lanes from the 101 Freeway to Skirball Center Drive. Connectors between the 101 and 405 freeways will also be shuttered during these hours to facilitate the work.

Timeline

  1. Closures are scheduled nightly from 9 p.m. to 6 a.m.

  2. The construction period runs from October 13, 2026, to October 17, 2026.

The Home Front

This project follows the maintenance pattern established by the California Department of Transportation pavement rehabilitation program. It reflects a continued regional focus on preserving highway infrastructure to manage the lifecycle of high-traffic transit corridors.

Drivers residing near the Sepulveda Pass should prepare for increased noise, vibrations, and dust throughout the five-night construction window. Use the official Caltrans QuickMap road conditions to check real-time traffic impacts before leaving your home.
