Topanga Canyon Highway Reconstruction Affects Sylvia Park Access Into 2027

SYLVIA PARK / TOPANGA, Los Angeles County — November 3, 2026. Residents traveling from Sylvia Park toward the coast or the San Fernando Valley use the same Topanga Canyon corridor covered by a major Caltrans pavement rehabilitation project. Work on State Route 27 resumed in June 2026 after disruptions caused by the 2025 Palisades Fire.

What is Caltrans doing?

The state describes an approximately $59.5 million rehabilitation contract covering more than 18 miles between Devonshire Street and Pacific Coast Highway. It includes pavement repairs, curb-ramp accessibility work, traffic signals, pedestrian push buttons, transit stop improvements and new guardrail sections.

How far along is the work?

Caltrans’ project page describes the overall program as about 65% complete and expects full completion in summer 2027. The southern section through Topanga resumed June 15, 2026, with generally overnight work hours. These are project updates; drivers must check current alerts before travel.

Why separate the contracts?

Caltrans is also conducting emergency repairs for prior wildfire and mudslide damage at a separate work zone on Route 27. Repairs and repaving overlap geographically, but their contracts, schedules and exact traffic controls differ. Residents should not mistake a reopened segment for completion of the entire project.
