Do you think overnight freeway closures for road repairs are worth it?

Caltrans is closing lanes, ramps and connectors on the 405 Freeway through the Sepulveda Pass from 9 p.m. to 6 a.m. on Monday, Thursday and Friday. The overnight work includes shoulder reconstruction and paving, with the speed limit reduced to 55 mph in some areas in both directions.

Why it matters

The closures affect a major Los Angeles commuter corridor, and drivers and nearby residents should expect overnight disruptions while the freeway work proceeds. The project is intended to improve safety and mobility and extend the life of the freeway pavement.

The $143.7 million pavement rehabilitation project carries overnight closures from 9 p.m. to 6 a.m. Monday, Thursday and Friday, with up to three northbound lanes closed between Sepulveda and Victory boulevards and up to four southbound lanes closed between the 101 Freeway and Skirball Center Drive.

The players

Caltrans

The California Department of Transportation is the state agency responsible for designing, building and maintaining California's highways, including the I-405.

The details

Intermittent closures will occur each night on northbound and southbound 405 lanes, ramps and connectors, with several ramps and 101 connectors closed on rotating nights. Residents and businesses near the construction may experience noise, vibrations and dust.

Overnight closures begin Monday evening.
Closures run from 9 p.m. to 6 a.m. Monday, Thursday and Friday.

Roadmap

The overnight work is part of the I-405 Pavement Rehabilitation Project between Van Nuys and Westwood, a multi-phase effort to resurface and rebuild the aging freeway pavement. It fits a broader state pattern of using off-peak nighttime closures to limit disruption to commuters while repairing heavily traveled corridors.

Drivers using the 405 through the Sepulveda Pass should plan around lane and ramp closures on Monday, Thursday and Friday nights, and expect reduced speeds of 55 mph in some areas. Commuters who rely on the northbound and southbound ramps may need alternate routes on nights when those connectors are closed.

The takeaway

Drivers who regularly use the 405 Freeway should check closure schedules before overnight trips and allow extra time on closure nights. Staying informed about rotating ramp closures can prevent unexpected detours.
