The California Department of Transportation (Caltrans) has announced a project to upgrade the tunnel lighting system and install a queue warning system at the McClure Tunnel on Interstate 10 (I-10) and State Route 1 (SR-1) in the city of Santa Monica. Overnight full closures of the McClure Tunnel and nearby ramps will occur during construction. The project will include the following: 

  • The work zone spans one-mile from Lincoln Blvd on I-10 to the Broadway Pedestrian Overcrossing on SR-1. Crews will upgrade the lighting system in the McClure Tunnel to LED lights for improved visibility.
  • A queue warning system, the first in Los Angeles County, will be installed on westbound I-10 to provide automatic, real-time alerts to motorists when queues accumulate at the McClure Tunnel. Motorists will be alerted if they need to slow down as they approach the tunnel. 
  • Additionally, the project will install a speed feedback sign, a high-friction surface treatment to the pavement inside the tunnel, and an upgrade to overhead signage in the project area.

Construction is scheduled to start the first week of January 2021. Overnight full closures of the McClure Tunnel will occur to facilitate a safe work zone. 

Detour signs will be posted for all full closures. Ramp closures associated with the project will occur mostly overnight between 7 p.m. and 6 a.m. Closures are weather-permitting and subject to change. Motorists should expect delays and are advised to use alternate routes during construction hours. Additionally, motorists can view current traffic closures before they leave for their destination by visiting the Caltrans Quickmap. Residents and businesses located near the freeway are advised to anticipate noise, vibrations, and dust associated with construction activities. Aldridge Electric is the contractor on this $6.3 million project, which is anticipated to be completed in Spring 2021.  Caltrans reminds motorists to “Be Work Zone Alert” and “Slow for the Cone Zone.”
