State Route 121-Between State Route 128 and Wooden Valley Road
Update-Closure Continues-Further Roadway Erosion

NAPA COUNTY– State Route 121 (SR-121) in Napa County remains closed until further notice for emergency roadway repairs. The closure is located on SR-121 between SR-128/Capell Valley Road and Wooden Valley Road. SR-121 was originally closed during last weekend’s storm on Sunday, March 13.

Since that time, the northbound SR-121 roadway has eroded further. Depending on weather and if no further roadway erosion occurs, Caltrans is tentatively scheduled to begin permanent repairs and install temporary one-way traffic signals near the site the week of March 28.

Temporary traffic signals will allow northbound and southbound SR-121 motorists to pass the erosion site by alternating use of the existing southbound SR-121 lane. Caltrans will continue to closely monitor the erosion site. At this time, the following detours remain in effect:

SR-121 Detours
Westbound SR-128 motorists headed to southbound SR-121 will be detoured to westbound SR-128 to SR-29. Motorists from Napa wanting to avoid the closure are advised to use northbound SR-29 to eastbound SR-128. Motorists from Wooden Valley Road will be detoured to southbound SR-121 to northbound SR-29, then eastbound SR-128. Local access only beyond SR-128/SR-121 intersection.
