Sierra/Nevada Counties – Caltrans is alerting Interstate 80 (I-80) east- and westbound motorists to expect continued rolling traffic breaks through September west of the California-Nevada border for mountain slope protection work.

Wire mesh drapery is suspended from a helicopter along the mountain slope of Interstate 80 for a rockfall protection project near the California-Nevada border.A contractor will be utilizing a helicopter to fly wire mesh drapery panels to the top of the mountainside near Mystic.

The California Highway Patrol (CHP) will perform rolling traffic holds along east- and westbound I-80 during the helicopter work. Traffic will be held in both directions for approximately 10 minutes before being released. Motorists should expect travel delays of up to 30 minutes due to queuing during traffic holds.

Helicopter work and rolling traffic breaks on I-80 are currently scheduled between 9 a.m. and 2 p.m. on the below dates. The construction schedule is subject to change based on weather, equipment and CHP availability or other unexpected events.

  • September 8
  • September 13-15
  • September 20-22
  • September 27-29

The improvements are part of a $12.6 million project to stabilize the cut slope along I-80 westbound just west of the California-Nevada state line to prevent continued rockfall onto shoulder areas and the roadway. The project will include flattening the existing slope, installing drapery systems, and constructing concrete barriers and valley gutters.

Alfaro Communications Construction, Inc. of Compton is the prime contractor for the project, which is scheduled to be completed in November.

The department will issue construction updates on Twitter @CaltransDist3, on Facebook at CaltransDistrict3 and on the Caltrans District 3 website. For real-time traffic, click on Caltrans' Quickmap or download the QuickMap app from the App Store or Google Play.
