Caltrans has scheduled nightly pavement rehabilitation closures on the 405 Freeway through the Sepulveda Pass from October 13, 2026, to October 17, 2026. Drivers should anticipate travel disruptions as crews install K-rail and perform road work.

Why it matters

The $143.7 million project aims to improve freeway safety and mobility while extending the functional life of the pavement. These upgrades are necessary to maintain the integrity of a critical transit corridor for Los Angeles residents.

The rehabilitation project carries a total budget of $143.7 million. During construction hours, speed limits in the work zone will be strictly reduced to 55 mph.

The players

Caltrans

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

The details

Crews will restrict access to specific freeway lanes, ramps, and 101 Freeway connectors to facilitate K-rail installation and paving. Residents and commuters in the area should prepare for increased noise, vibrations, and dust during the overnight work periods.

Timeline

  1. October 13, 2026 to October 17, 2026

  2. 9 p.m. to 6 a.m. nightly

Roadmap

This project represents a broader initiative by state agencies to modernize aging freeway infrastructure through intensive pavement rehabilitation. These systemic upgrades reflect the ongoing commitment to extending the lifespan of vital arterial roads amidst increasing urban traffic demands.

Drivers using the 405 Freeway should expect nightly delays and must adhere to the reduced 55 mph speed limit within the construction zone. Local commuters are advised to plan for alternative routes between the 101 Freeway and the Skirball Center Drive area to avoid closure bottlenecks.

The takeaway

Drivers should remain vigilant for changing traffic patterns and reduced speed limits during the overnight hours to ensure safety for themselves and road crews. Planning ahead for travel delays will help mitigate the impact of these temporary, yet essential, infrastructure improvements.
