Caltrans announces Highway 99 culvert replacement project

The California Department of Transportation and Lamb Unlimited General Engineering are preparing to begin work on the Butler Slough Culverts Project on Highway 99 in Tehama County. The $611k project will provide culvert replacement at five locations near Los Molinos, from Second Avenue to just north of Cone Grove Road.

Construction activities are currently planned to start on Monday, Oct. 14. Motorists will encounter nighttime one-way traffic control with up to 10-minute delays, Monday through Friday between 7 p.m. and 7 a.m. daily. 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 mid-November, pending weather.

Construction projects are subject to changes without prior notice. Caltrans and its contractors do our best to keep the public informed.
