Pavement Project on State Route 139 in Lassen & Modoc Counties

SR 139

Caltrans District 2, in conjunction with Hat Creek Construction & Materials, Inc., is preparing to begin work on a pavement project on State Route 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 State Route 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 on Monday, August 9. Motorists will encounter one-way traffic control with up to 14-minute delays during daytime hours, Monday-Friday. The project is currently anticipated to be completed by the end of October.
