State Route 128-Napa/Sonoma County Line Overnight One-Way Traffic Controls Roadway Repair Work Two Consecutive Nights Start Thursday, May 9, 2018

NAPA COUNTY— The California Department of Transportation (Caltrans) will perform pavement repair work on State Route 128 (SR-128) near the Napa/Sonoma county line. 

The work will repair a section of SR-128 affected by last October’s Wine Country Fires. 

One-Way Traffic Controls on SR-128

To ensure public and worker safety, one-way traffic controls will be in effect on SR-128 between the Napa/Sonoma county line and approximately ½ mile just east of the county line.

Crews will alternate lane closures in both northbound and southbound directions. This will allow one traffic lane on SR-128 to remain open during the work.

The work will be performed on SR-128 on Thursday, May 9 and Friday, May 10. Work will start each night at 6:00 PM until 6:00 AM the following mornings. Flaggers will help direct traffic.

All work is weather permitting.  Motorists should expect delays and allow for extra travel time.
