NAPA COUNTY, CA — Caltrans announced a detour for bicyclists traveling near the SR-29/221 Soscol Junction Interchange just south of the city of Napa.

About The Soscol Junction Interchange Project

Construction began July 25 on the project after a delay by Swanson Hawks that were nesting in the area.

The three-year project will replace the signalized intersection of State Route 12/29, State Route 221 and Soscol Ferry Road with an interchange composed of an overpass and two roundabouts, a configuration that will add fluidity to traffic flow, reduce congestion and enhance bicycle and pedestrian connectivity, Caltrans said in a news release.

Caltrans crews will landscape the area with local plants, including oaks whose canopies will visually screen the interchange from distant onlookers.

Caltrans will build 1,200 feet of Class I bicycle and pedestrian paths as part of the project. Eventually, the bicycle/pedestrian lanes will connect to the Vine Trail, a 47-mile multi-use path that will stretch from Calistoga to the ferry in Vallejo.
