If there’s one thing Southern Californians know, it’s that getting around by car can mean navigating a constantly shifting maze of lane closures, construction zones, and unexpected delays. With so much of daily life built around driving, staying on top of traffic updates can make the difference between a manageable commute and a very long night behind the wheel.
This week, drivers on one of L.A.’s major freeways should plan for some extra roadwork: the 101 Freeway will face a series of lane and ramp closures through the Cahuenga Pass as Caltrans continues a long-term pavement rehabilitation project.
The closures will affect northbound traffic along nearly 4 miles of the 101, between Highland Avenue and State Route 170, with up to three lanes closed at a time.

The shutdowns are scheduled from Monday, August 17 through Saturday morning, August 22, although Caltrans notes that the schedule could change due to weather or operational needs. Here’s what drivers can expect:
⛔ Monday night, August 17 through Friday morning, August 21:
- Up to three northbound lanes between Highland Avenue and SR-170 will close from 10 p.m. to 6 a.m.
- The eastbound Universal Studios Boulevard on-ramp to northbound 101 will close from 9 p.m. to 6 a.m.
- The westbound Universal Studios Boulevard/W.C. Fields Drive on-ramps to northbound 101 will close from 10 p.m. to 6 a.m.
⛔ Friday night, August 21 through Saturday morning, August 22:
- Up to three northbound lanes will close from 10 p.m. to 9 a.m.
- The eastbound Universal Studios Boulevard on-ramp will close from 9 p.m. to 11 a.m.
- The westbound Universal Studios Boulevard/W.C. Fields Drive on-ramps will close from 11 p.m. to 11 a.m.
One change worth noting: the westbound Ventura Boulevard/Campo de Cahuenga Way on-ramp to northbound 101 will remain open.
Caltrans is advising motorists to allow extra travel time, follow posted detour signs, and use QuickMap for the latest road conditions.
The closures are part of a $24.3 million rehabilitation project that will improve pavement, ramps, shoulders, guardrails, concrete slabs, traffic striping, and pedestrian accessibility along the Cahuenga Pass. Construction is expected to continue through summer 2029.
