The Napa Valley Transportation Authority (NVTA) is a Congestion Management Agency formed in 1998 as a joint effort by the cities of American Canyon, Calistoga, Napa, St. Helena, the town of Yountville and the County of Napa in the state of California. NVTA serves as the countywide transportation planning agency. The agency's goals, duties and composition make it easier for local governments to tackle the increasingly complex problem of traffic congestion. NVTA also operates the Vine Transit, Napa Valley's bus system. But we also have other responsibilities: we oversee the planning and funding of paratransit (transportation for special needs and disabled riders), the maintenance and improvement of highways, streets and roads, and bicycle transit.
