Installing slope protection system requires additional one-way traffic for 2-4 weeks
LOS ANGELES – Starting Monday, Oct. 13, crews will begin one-way traffic control for about one-tenth of a mile from Fernwood Pacific Drive to Grand View Drive to work on a slope restoration project north of the unincorporated Los Angeles community of Topanga.
The one-way traffic control area will operate from 9 a.m. to 5 p.m. weekdays. The work is expected to last two to four weeks.
During these hours, traffic control flaggers will enforce one-way traffic for this short stretch. Outside of these hours, all travel lanes in this section will be open without restriction.
The project involves installing a gabion basket, a wire-mesh structure filled with rocks that acts as a retaining wall and catches debris for slope stability, along the hillside near mile marker 3.7, just north of Grand View Drive.
The work is in response to a landslide that happened in late 2024. It was postponed due to the 2025 Palisades Fire and subsequent winter storms.
This project’s limits are just north of the 3.6-mile stretch of SR-27 between PCH and Grand View Drive that is an active work zone for ongoing recovery efforts from the Palisades Fire and winter storms.
This project is in addition to Caltrans’s one-way traffic control section with a pilot car for four-tenths of a mile just south of Topanga, which operates from 5 a.m. to 11:59 p.m. daily. That stretch of road remains closed to the public from midnight to 5 a.m. daily.
Southern California Edison also has one-way traffic control from 8:30 a.m. to 5:30 p.m. daily on SR-27 from Topanga Library to Happy Trail.
For the safety of workers and one another, motorists must obey the 25-mph speed limit in the work zones, along with any posted signs and traffic controllers. There is no parking, no stopping and no pedestrians allowed in the work zones.
Motorists are advised to take extra caution, especially around blind curves in case of stalled traffic at one-way sections, as fines can be doubled in a work zone.
