NORTHERN CALIFORNIA – Construction signs have been installed for a slope protection project on Highway 128/Oat Valley Road in Sonoma County.

The project is located two miles west of the three-way intersection of North Cloverdale Boulevard/ North Redwood Highway/Oat Valley Road, and approximately 1.8 miles east of the Mendocino County line.

Construction will continue through October 2015.
 
Groundbreaking activities are expected to begin the week of April 6. Please be alert for construction workers and follow the directions of flaggers.

One-way reversing traffic control will be in place during this project, and motorists should expect delays when traveling through the construction zone.

Starting in late April or early May, the width of Highway 128 roadway will be temporarily reduced at a hair-pin curve so big rigs will not be able to travel through the construction zone.

The segment of Highway 128 between N. Cloverdale Boulevard and Highway 253 will be closed to big rigs over 30 feet in length.

Portable changeable message signs will be in place one week prior to alert drivers regarding the closure for big rigs. Big rigs will be detoured to Highway 253.
 
A second slope protection project will begin in May, approximately 2.4 miles east of the Mendocino County line.

This project will not have a big rig restriction, but the restriction will remain in effect until the completion of the previously mentioned project.
 
If this work is delayed due to weather conditions, it will be rescheduled for a later time. Please drive cautiously through the construction zone, leave a safe traveling distance between your vehicle and the vehicle ahead of you, and Slow for the Cone Zone.
