Caltrans closes lanes, ramps and freeway connectors on the I-405 through the Sepulveda Pass on three nights this week for the 405 Pavement Rehabilitation Project. Work runs from 9 p.m. to 6 a.m. on Monday, Nov. 9, and on Thursday and Friday, Nov. 12 and 13, according to a Caltrans notice reported on Nov. 8. No closures are listed for Nov. 10 or 11.
What closes during the 405 Pavement Rehabilitation Project work
Northbound, crews close up to three lanes from Sepulveda Boulevard to Victory Boulevard. They also close up to three lanes from Wilshire Boulevard to Skirball Center Drive/Mulholland Drive. The Sepulveda Boulevard on-ramp closes, along with the on- and off-ramps at Burbank Boulevard and Getty Center Drive.
Southbound, up to four lanes close from U.S. 101 to Skirball Center Drive/Mulholland Drive. The Burbank Boulevard on-ramp closes, and so do the on- and off-ramps at Sepulveda Boulevard.
Three freeway connectors also close: northbound 101 to southbound 405, northbound 101 to northbound 405, and southbound 101 to northbound 405.
How to plan your drive
The notice does not list fixed detour routes. Instead, Caltrans points drivers to Caltrans QuickMap for live conditions. Because the connectors from the 101 close, drivers heading to the Westside from the Valley should allow extra time and check QuickMap before leaving.
Caltrans also lowers the speed limit to 55 mph through active work zones in both directions. In addition, weather or operational problems can change closure times, locations or lane setups at the last minute. Nearby residents may notice noise, vibration and dust overnight.
About the project
The $143.7 million project repaves about 10.2 miles of the 405 between Van Nuys and Westwood. According to the Caltrans project page, construction began in summer 2025 and should finish in winter 2027. The 55 mph limit and uneven pavement should last through winter 2026 and early spring 2027.
Caltrans expects a mix of closures over the life of the work: weeknight lane closures, about 25 extended weekend lane closures and 15 to 20 brief full overnight closures. Crews pause work for special events and state holidays. For earlier closures, see our report on overnight lane and ramp closures through Oct. 23.
