Drainage Project In Napa To Close Northbound Highway 29 Shoulder

NAPA, CA — Caltrans is scheduled to start work Monday on a drainage systems project on state Highway 29 in the city of Napa.

A crew will spend about two weeks removing trees from the project area, which starts a 10th of a mile north of the First Street Overcrossing and ends a 10th of a mile south of the Trancas Street Overcrossing.

Lane closures will affect the on- and off-ramps at Lincoln Avenue. The work will be done overnight from 9 p.m. to 5 a.m. to minimize traffic impacts, according to a traffic advisory from Ryan Leong, a Bay Area spokesperson for Caltrans.

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.

Leong expects construction of the drainage project to continue through December 2025.

"All work depends on weather," Leong said. "Please drive with caution. Slow for the Cone Zone
and Be Work Zone Alert."
