Welcome to the Napa County Roads Division. We are committed to maintaining and preserving the Napa County road system so that it is safe, reliable and accessible for all users. The Roads division is responsible for maintaining approximately 450 miles of public roads, 79 bridges and 50 major drainage structures within the unincorporated area of the County. The division is active in other road-related safety efforts such as vegetation management and maintenance of structure, drainage facilities, guardrails, traffic signs, signals and pavement markings. We invite you to visit our links page for useful road and safety links.
Construction of Devlin Road south of Airport Boulevard will begin June 18 and continue through the Fall. Initial operations will include clearing the site and bringing in fill material. Minor delays may occur on Airport Boulevard during these operations. Please visit the Devlin Road Extension for more information.
