The California Department of Transportation will shut down Hawthorne Boulevard tonight.

It will be closed in both directions this week to install new loop detectors, which are road sensors used to monitor traffic flow and overall highway performance. Closures will start at 10 p.m. and end at 6 a.m. between Sepulveda boulevard and Pacific Coast Highway. It’s part of a $5 million dollar emergency pavement project on Hawthorne Boulevard from PCH to Fashion Way. It started in September and includes replacing damaged asphalt, re-striping lanes and detectors.

This weekend, closures will start earlier at around 3 pm in the afternoon.
