Brace yourselves, Angelenos – the infamous 405 is going to shrink this weekend from January 9-12, 2026. Caltrans has announced extended lane reductions along the Sepulveda Pass, and it’s going to be a traffic crawl if you’re not prepared.
🚗Road Closures: When & Where
Commuters can expect extended weekend reductions from 10 p.m. on Friday, Jan. 9, through 5 a.m. Monday, Jan. 12.
Drivers traveling along I-405 will experience the following lane reductions and ramp 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

- Skirball Center Drive/Mulholland Drive on-ramp closed
🚗Alternate Routes to Outsmart Traffic
- Sepulveda Boulevard to northbound I-405: Travel north on Sepulveda Boulevard and then east/north on Skirball Center Drive to the on-ramp to northbound I-405
- Sepulveda Boulevard to southbound I-405: Travel south on Sepulveda Boulevard and then south on Church Lane to the Sunset Boulevard on-ramp to southbound I-405
🚗What to Expect
These extended weekend lane reductions aren’t a one-time occurrence. Caltrans plans about 25 weekends of lane closures along the 405 through this project. Nearby residents and businesses should expect some extra noise, dust, and vibrations.

🚗Why It’s Happening: The $143.7 Million Makeover
These aren’t random road closures. The I-405 Sepulveda Pass Pavement Rehabilitation Project is underway between Van Nuys and Westwood along the Sepulveda Pass. Caltrans is dropping $143.7 million to:
- Improve safety
- Enhance mobility
- Extend pavement life
The headache of weekend traffic re-routes is a small price to pay for improved transportation in the long run.
