Napa County—Caltrans has scheduled temporary single-lane overnight closures on State Route 121 (SR-121) from the Napa-Sonoma county line to the intersection of SR-121 and SR-29 in Napa in late July and early August. One lane will be open at all times.

One lane of SR-121 is scheduled to be closed at 10:00 PM Wednesday, July 24, re-opening at 5:00 AM Thursday, July 25. One lane will also be closed at 10:00 PM Thursday, July 25, re-opening at 5:00 AM Friday, July 26.

On Monday, July 29, one lane of SR-121 will close between 10:00 PM and 5:00 AM Tuesday.

Starting Sunday, August 4 and running through Thursday, August 16, the temporary single-lane closures will take place Sunday through Thursday, 10:00 PM to 5:00 AM.

During the lane closures, there will be one-way traffic control, with flaggers directing traffic. The lanes will be closed to accommodate paving and resurfacing of SR-121 to eliminate bumps and potholes.

Caltrans thanks motorists for their patience as we work to improve the highways.
