Caltrans will implement overnight lane and ramp closures on the 405 Freeway between October 26 and October 30, 2026. This construction is part of a pavement rehabilitation project spanning from Van Nuys to Westwood.
Why it matters
The project aims to improve safety and mobility while extending the life of the freeway pavement in a heavily traveled area. Local residents and businesses should anticipate noise, vibrations, and dust during the construction work.
The pavement rehabilitation project carries a total cost of $143.7 million and requires lane closures between 9 p.m. and 6 a.m. Speed limits in affected construction zones are reduced to 55 mph.
The players
Caltrans
The California Department of Transportation is the state agency responsible for the design, construction, and maintenance of California's highway system.
The details
Crews are performing K-rail installation and paving work, necessitating the closure of multiple lanes and specific on- and off-ramps along the Sepulveda Pass. Affected sections include closures between Sepulveda and Victory boulevards, as well as segments from Wilshire Boulevard to Skirball Center Drive.
Timeline
Overnight closures will occur from Monday, Oct. 26, to Friday, Oct. 30, 2026.
Roadmap
This project aligns with the broader state strategy to maintain and modernize California's aging highway infrastructure. It reflects ongoing efforts to reduce long-term maintenance costs through proactive pavement rehabilitation.
Commuters should expect significant delays and plan for slower travel times due to the 55 mph speed limit restriction. Drivers are advised to check real-time traffic updates to account for ramp closures and lane limitations during the overnight work.
The takeaway
Travelers should utilize alternative routes if possible to avoid construction-related traffic congestion during the week. Monitoring official road condition maps can help drivers adjust their schedules to minimize time lost during the closure period.
