Expect traffic impacts on SR 29 due to Silverado Trail repair near St. Helena as well as Airport Blvd closure in South Napa

Heavy traffic and delays are anticipated around two project sites in Napa County.

1. Traffic delays in South Napa on SR 29 due to road work at Airport Blvd

The Airport Blvd exit from SR 29 and the intersection at Devlin and Airport Blvd in Napa will be closed this afternoon through tomorrow morning due to ongoing roadwork in this area. Traffic is being directed to a detour route around the project, but commuters should expect traffic delays. Previously this work had been scheduled to occur the week of October 18 but was delayed due to rain.


​​​​​​2. Traffic delays near St. Helena due to Silverado Trail repair

Yesterday, the County installed a temporary stoplight at Highway 29 and Deer Park Road. While the temporary stoplight has helped ease traffic congestion, commuters should continue to expect delays when traveling Highway 29. The County has retained a contractor, who will begin work to repair the washout at Silverado Trail tomorrow, Friday, October 29. The County is working to reopen the impacted section of Silverado Trail as swiftly as possible.

Commuters are encouraged to carpool, budget more time for trips, and avoid unnecessary travel when possible.
