Single lane Closures Scheduled on Northbound State Route 29 (SR 29) For Drainage System Project in Napa County

Schedule: Project starts Monday, Dec. 9 from 9 p.m. to 5 a.m.

Napa County - Caltrans is scheduled to start work on a drainage systems project on State Route 29 (SR-29) in the city of Napa from 0.1 of a mile north of Trancas Street Overcrossing starting on Monday Dec. 9.

A crew will remove trees within the project limits for a duration of two weeks. To minimize traffic impact, the work will be done at night from 9 p.m. to 5 a.m. The on-ramp and off-ramp at Lincoln Avenue will be affected by the lane closures.

Following the tree removal, the contractor will install temporary concrete barriers (k-rails) and crash cushions and close the northbound shoulder of SR-29 within the project limits. The construction work for this project will continue through December 2025.

All work depends on weather.

Please drive with caution. Slow for the Cone Zone and Be Work Zone Alert.
