Project Scope

Napa County is proposing to improve the intersection for Devlin Road and Soscol Ferry Road with construction of a roundabout. The project would convert the intersection into a yield-controlled, single-lane, three-legged roundabout designed to accommodate future traffic forecasts. There would be no expansion in the number of travel lanes for Devlin Road and Soscol Road, but minor expansion of right-of-way is necessary to accommodate the roundabout.  Additional improvements would include the installation of a multi-modal pathway and pedestrian crossings, lighting, as well as restriping and landscaping.  The project is located south of the City of Napa immediately southwest of the intersection of State Routes 29, 221 and Soscol Avenue within the Napa Valley Business Park (aka – Napa Airport Industrial Park).  Adjacent to Assessor’s Parcel Numbers 057-170-020, -021, -004, -015, & -016, and 046-400-026, & -020.
