Caltrans announces Highway 139 pavement project

The California Department of Transportation, in conjunction with Hat Creek Construction and Materials, Inc., is preparing to begin work on a pavement project on Highway 139 in portions of Lassen and Modoc counties near Adin. The $3.9 million project will provide cold-in-place recycling on the existing pavement with a hot mix asphalt overlay from approximately 4.5 miles south of County Road A2 to just south of the junction with Hghway 299. The project will also include shoulder backing, upgrading guardrail to current standards, and removal and replacement of thermoplastic pavement markings.

Construction activities are anticipated to begin Monday, Aug. 9. Motorists will encounter one-way traffic control with up to 14-minute delays during daytime hours, Mondays – Fridays. Motorists are urged to slow down and drive carefully in and around construction areas, follow speed limit reductions in place, and allot extra time for delays. The project is currently anticipated to be completed by the end of October.

Construction projects are subject to changes without prior notice.                   Caltrans and its contractors do our best to keep the public informed.  To stay up to date on highway projects, please follow us on Facebook and Twitter.  Project information can also be found on the District 2 webpage. The public can also call 225-3426 during working hours or send an email to
