Overnight lane closures will be in effect beginning Monday along a stretch of Topanga Canyon Boulevard for continued guardrail and shoulder work, Caltrans officials said Friday.
One lane of Topanga Canyon Boulevard/State Route 27 between Cezanne Avenue and Pacific Coast Highway will be open to traffic in both directions from as early as 10 p.m. to as late as 6 a.m. Monday night through Saturday morning, according to Caltrans.
Flaggers will direct alternating traffic through the open lane where crews are working. The locations of the one-way traffic controls may move throughout the night, with signs posted to alert motorists traveling in both directions.
The closures are scheduled to continue nightly through Aug. 29, weather permitting, and are subject to change.
Motorists were advised to expect delays and consider alternate routes during construction hours.
Caltrans also advised residents and businesses near the highway to expect construction-related noise, vibrations and dust.
The guardrail and shoulder work is part of a pavement rehabilitation project along more than 18 miles of State Route 27 from Pacific Coast Highway to Devonshire Street in Chatsworth.
The project also includes repaving and upgrades to curb ramps, pedestrian push buttons and bus pads in the San Fernando Valley and the unincorporated Topanga area.
Work on the San Fernando Valley portion of the project has been completed, according to Caltrans.
The overall project is expected to be completed in summer 2027.
