Southern California drivers who navigate the Cahuenga Pass are advised to prepare for significant overnight lane, ramp, and connector closures on the Hollywood (101) Freeway, beginning Monday evening and continuing through Saturday morning. The closures are part of a substantial $24.3 million pavement rehabilitation project, according to Caltrans.
The work will affect both northbound and southbound lanes, with varying restrictions each night. On Monday and Tuesday nights, northbound 101 Freeway traffic between Highland Avenue and the 170 Freeway will be reduced to two lanes starting as early as 10 p.m. until 6 a.m. During the overnight hours of 2 a.m. to 4 a.m., only a single lane will be open. Southbound traffic will see similar reductions on these nights, with three lanes closed from as early as 9 p.m. to 5 a.m., narrowing further to just one available lane between 2 a.m. and 4 a.m., Caltrans announced.
From Wednesday night through Friday morning, the lane closures will shift. Northbound, up to three lanes will be closed between Highland Avenue and the 170 Freeway from as early as 10 p.m. to 6 a.m., with up to four lanes closed for two hours, from 2 a.m. to 4 a.m. Southbound 101 Freeway drivers can expect up to two lanes to be closed from as early as 9 p.m. to 5 a.m. during this period.
The final stretch of overnight work, from Friday night into Saturday morning, will bring further closures. Up to three northbound lanes on the 101 Freeway will be closed from 10 p.m. to 9 a.m., with a more restrictive period from 4 a.m. to 5 a.m. seeing up to four lanes closed. Southbound, up to two lanes will be closed from 10 p.m. to 9 a.m.
Beyond the main freeway lanes, several connector ramps will also be closed overnight through Friday morning. Additionally, numerous on- and off-ramps along the route may experience closures during the specified construction hours. Detour routes will be clearly marked for affected motorists, and Caltrans advises allowing additional travel time to account for the disruptions.
The project itself is a comprehensive effort to rehabilitate asphalt on freeway lanes, ramps, and shoulders, alongside replacing or repairing concrete slabs. Crews are also tasked with replacing guardrails, curbs, dikes, a crash cushion, and traffic striping. Furthermore, 23 curb ramps along the corridor will be upgraded to meet accessibility standards. While these immediate closures are a temporary inconvenience, the full pavement rehabilitation project is not expected to be completed until summer 2029.
