Hopland 101 Project

Caltrans proposes to construct improvements on U.S. Highway 101 in downtown Hopland in Mendocino County (post miles 10.7 and 11.2) for compliance with the Americans for Disabilities Act (ADA). Work would include improving curb ramps, sidewalks, and driveways, reconstructing the roadway, rehabilitating pavement, and signage.

The purpose of the proposed project is to improve the safety and accessibility of pedestrian facilities in downtown Hopland in conformance with the ADA, and to improve, pavement, and signage.

Traffic Delays

Motorists traveling in Hopland between the Feliz Creek Bridge and north of First Street should anticipate up to 15-minute delays during overnight hours from 8 p.m. to 6 a.m., Sunday through Thursday. Expect delays at Mountain House Road and at Route 175. Posted speed limits will be reduced to 25 mph during construction and motorists are asked to drive with caution in the work zone.
The project will operate on a continuous schedule, running 24 hours a day from Sunday at 8 a.m. through Friday at 7 a.m. This approach is designed to minimize the overall project timeline and enhance safety for both workers and the public.

All businesses are open during construction. Temporary impacts to parking and access may occur within the work area, but measures will be taken to limit disruptions.
