Overnight Closures Hit I-405 Through the Sepulveda Pass on November 9, 12 and 13, From 9 p.m. to 6 a.m.
Overnight lane, ramp and connector closures begin Monday evening, November 9, along Interstate 405 through the Sepulveda Pass in Los Angeles, and repeat on Thursday, November 12 and Friday, November 13, from 9 p.m. to 6 a.m. each night, for shoulder reconstruction and paving, Caltrans said. The speed limit drops to 55 mph in some work areas in both directions.
On the northbound side, up to three lanes close between Sepulveda and Victory boulevards, along with the Getty Center Drive and Burbank Boulevard ramps and the Sepulveda Boulevard on-ramp, and up to three more lanes close between Skirball Center Drive/Mulholland Drive and Wilshire Boulevard. Southbound, the Sepulveda Boulevard ramps close, up to four lanes close between the Ventura (101) Freeway and Skirball Center Drive/Mulholland Drive, the Burbank Boulevard on-ramp closes, and three 101 connectors are affected: northbound 101 to southbound 405, northbound 101 to northbound 405, and southbound 101 to northbound 405.
The work is part of the $143.7 million I-405 Pavement Rehabilitation Project, which covers a 10.2-mile stretch between Van Nuys and Westwood, replacing sections of two lanes in each direction from Victory Boulevard to Mulholland Drive, with completion expected in winter 2027. Caltrans said nearby residents and businesses may experience noise, vibration and dust, and advised drivers to check Caltrans QuickMap for current conditions.
