    • The 405 Freeway through the Sepulveda Pass will have weekend closures and reductions in both directions for paving work.
    • The closures are in effect 10 p.m. Friday, Dec. 19 through 5 a.m. Monday, Dec. 22.
    • The closures are part of a larger $143.7 million pavement rehabilitation project to improve safety.

LOS ANGELES - Drivers should prepare for slowdowns and backups on the 405 Freeway 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.

Lane reductions, closures

What we know:

Paving work will start at 10 p.m. Friday, Dec. 19 through 5 a.m. Monday, Dec. 22.

Motorists traveling along the 405 Freeway will experience the following lane reductions and closures:

Northbound I-405

  • Reduced to three lanes between just south of Getty Center Drive/Sepulveda Blvd. off-ramp to just north of Bel Air Crest Road
  • Getty Center Drive/Sepulveda Boulevard off-ramp closed

Southbound I-405 

  • Reduced to three lanes between Skirball Center Drive/Mulholland Drive on-ramp to Getty Center Drive/Sepulveda Blvd. on-ramp
  • Getty Center Drive/Sepulveda Boulevard on- and off-ramps closed
  • Skirball Center Drive/Mulholland Drive on-ramp closed 

What are alternate routes?

Local perspective:

  • Sepulveda Boulevard to northbound I-405: Take Sepulveda Boulevard instead of the freeway, then travel east/north on Skirball Center Drive back to the freeway.
  • Sepulveda Boulevard to southbound I-405: Take Sepulveda, then go south on Church Lane to the Sunset Boulevard on-ramp to the freeway.

I-405 Pavement Rehabilitation Project

Big picture view:

This is all part of the I-405 Pavement Rehabilitation Project between Van Nuys and Westwood. The $143.7 million project aims to improve safety and mobility along the heavily-trafficked freeway and extend pavement life.

Caltrans officials said extended weekend lake closures and reductions will happen about every two weeks along various sections of the 405.
