Overnight lane closures planned on 405 through Sepulveda Pass this week

Caltrans crews will reduce lanes and close a key ramp nightly between Wilshire Boulevard and U.S. 101.

Overnight lane reductions and ramp closures are planned this week on Interstate 405 through the Sepulveda Pass as crews conduct construction work, according to Caltrans.

The closures are scheduled to begin after 9 p.m. Monday, March 9, and continue nightly through 6 a.m. Saturday, March 14. The work will involve installing K-rail barriers and performing electrical upgrades along the freeway corridor.

Drivers traveling through the area between Van Nuys and Westwood should expect intermittent lane reductions and ramp closures during overnight hours.

Planned impacts include the closure of up to two northbound lanes of the 405 between Wilshire Boulevard and the Skirball Center Drive/Mulholland Drive interchange. The northbound off-ramp to Skirball Center Drive and Mulholland Drive will also be closed during the overnight work period.

Additional lane reductions are scheduled along northbound lanes between Skirball Center Drive/Mulholland Drive and Sepulveda Boulevard.

Southbound traffic will also be affected. Up to two lanes are expected to close between Skirball Center Drive/Mulholland Drive and Wilshire Boulevard, as well as between U.S. 101 and the Skirball Center Drive/Mulholland Drive interchange.

The work is part of Caltrans’ Interstate 405 Pavement Rehabilitation Project, which covers the stretch of freeway through the Sepulveda Pass. The $143.7 million project aims to improve safety and mobility while extending the life of the roadway between Van Nuys and Westwood.

Caltrans said construction schedules could change due to weather or operational factors, including adjustments to closure times or locations.

Residents and businesses near the construction zone may experience temporary noise, vibrations, and dust associated with the work.

Drivers are encouraged to check current traffic conditions through the Caltrans QuickMap website and are reminded to slow down in work zones as crews carry out the overnight improvements.
