FOR IMMEDIATE RELEASE

State Route 121-Napa County
Emergency Closure-Due to Rock Slide
Highway Closed between Vichy and Wooden Valley Road

NAPA COUNTY – State Route 121 (SR-121) in rural Napa County between Vichy and Wooden Valley Road remains closed due to an overnight rock slide.

The highway will remain closed until further notice until Caltrans geologists are able to determine if and when the rocks above the roadway have stabilized.

During the closure, Southbound SR-121 detour is State Route 128 (SR-128) to Silverado Trail. Northbound detour is Silverado Trial to SR-128.

Partial local access is available for residents only.

SR-121 connects communities near Lake Berryessa in rural Napa County with the City of Napa.

Caltrans will make an announcement once additional information is available.

Motorists should expect delays.

The site of this week’s rockslide is not related to a separate closure of SR-121 which occurred last year. This week’s rock slide on SR-121 is approximately four-miles south of last year’s SR-121 washout site where floodwaters undermined the highway. The washout site remains partially open.
