Drivers should prepare for slowdowns and backups on the San Diego (405) Freeway starting Friday evening and continuing through the weekend, as Caltrans closes several ramps on and off the freeway and reduces traffic to three lanes in both directions in the Sepulveda Pass.
“This work is part of the I-405 Pavement Rehabilitation Project between the Los Angeles communities of Van Nuys and Westwood along the Sepulveda Pass,” according to a Caltrans statement. “This project will apply about $143.7 million toward improving the safety and mobility along I-405 between Van Nuys and Westwood as well as extend the pavement life.”
The pavement rehabilitation project runs between Santa Monica Boulevard to just north of Sunset Boulevard, according to Caltrans.
The extended weekend lane reductions are set to begin Friday night at 10 p.m. until 5 a.m. Monday.
The freeway will be reduced to three lanes in each direction and motorists are urged to use alternate routes or public transportation.
On the northbound side, the 405 will be reduced to three lanes from just south of Getty Center Drive/Sepulveda Boulevard to just north of Bel Air Crest Road. The Getty Center/Sepulveda off-ramp will be closed.
On the southbound side, the 405 will be reduced to three lanes from Skirball Center Drive/Mulholland Drive to Getty Center/Sepulveda. The Getty Center/Sepulveda on- and off-ramps will be closed, along with the Skirball Center/Mulholland on-ramp.
Northbound motorists were urged to take Sepulveda Boulevard instead of the freeway, then travel east/north on Skirball Center Drive back to the freeway. Southbound motorists can also take Sepulveda, then go south on Church Lane to the Sunset Boulevard on-ramp to the freeway.
Similar lane closures are planned on additional weekends as the project progresses. Residents and businesses near construction sites may hear noise or experience vibrations and dust, Caltrans officials said.
