Soscol Junction Traffic Update

Traffic Update: Soscol Ferry Road to Highway 29 will close on December 13 as construction continues. Drivers should use Devlin Road to Airport Road to get to Highway 29.

Starting December 13, drivers on Soscol Ferry Road won't be able to get directly to Highways 221 and 29 in South Napa.

Instead, if you need to get to one of the highways from Soscol Ferry Road, take Devlin Road to Airport Blvd. to Highway 29. From there, you can go north or south on Highway 29, or you can travel north to get to Highway 221.

Southbound drivers on Highway 29 in South Napa County will still be able to turn right onto Soscol Ferry Road.

The closure will allow construction crews to:

  • Start building a temporary connector ramp for northbound Highway 221 in January 2023.
  • Close off the Soscol Ferry Road connector to Highway 29.

These closures will take place until the project is completed in summer 2024.
