The California Department of Transportation (Caltrans) plans a slope restoration project at postmile 4.9 on State Route 27 (SR-27) south of Circle Trail beginning Tuesday, Aug. 20. The work will require reducing about a half-mile of SR-27 to one lane with flaggers directing alternating traffic during off-peak hours, 9 p.m. to 6 a.m., for four weeks. Signs will be posted. Motorists can expect delays.
The slope along Topanga Creek was seriously eroded by February rainstorms, which undermines a section of the southbound roadway shoulder. Caltrans’ aim is to rebuild the slope with native dirt and rocks before the rainy season.
What the work involves:
- One lane closure from 9 p.m. to 6 a.m. Monday through Thursday.
- Extended one lane closure Friday to Saturday — 9 p.m. to 8 a.m.
- Hours were determined to avoid disrupting peak commuting periods.
- K-rails will be installed along the southbound fog line as a safety measure.
- Daytime slope repair work behind k-rails.
- Flaggers will communicate via radio to minimize traffic delays in both directions.
- Motorists will have access to Circle Trail.
- In the event of an emergency such as evacuation due to fire danger, work will be suspended to open lanes in both directions.
- The public can submit questions to Topanga@dot.ca.gov.
The contractor is Flo Engineering of West Covina.
All work is subject to change due to weather or construction-related issues. Residents and businesses located near the freeway may experience noise, vibrations and dust associated with construction activities.
