Purpose of this Plan
This project will create a "Gateway Corridor Improvement Plan" for State Route 29 between the cities of Vallejo and Napa, passing through the City of American Canyon and portions of unincorporated Napa County. This route is one of the most significant transportation corridors in Napa County. The planning effort will bring together diverse  stakeholders from throughout the community and will consider the part played by all transportation modes including ferry, auto, truck, bus, rail, air, bicycle and pedestrian. The plan will address the needs of residents, visitors, businesses and school children focusing on community-based solutions to improve corridor safety, aesthetics and  mobility.

The project will address 13.3 miles of the SR29 corridor between the City of American Canyon and the Trancas St. Park and Ride lot in north Napa. It will also address linkages to the Vallejo Transit Center/Ferry Terminal, the new downtown Napa transit center (scheduled to open in winter 2012) and incorporate input from planning work currently underway in the Sonoma Boulevard corridor (SR29) in the City of Vallejo. Two thirds of the project effort will be devoted to SR29 in American Canyon. 

The route passes through both urban and rural areas as well as industrial/business parks adjacent to the Napa County Airport, and adjoins an active freight rail line. There is existing fixed route and paratransit bus service along the corridor. A continuous Class 1 bikeway (The Napa Valley Vine Trail) is currently being planned and built along the corridor and extensive additional bicycle facilities are also being planned nearby in association with the Bay Trail program. The corridor also serves the Napa County airport and nine industrial/business parks located between the Cities of Napa and American Canyon. Altogether this is the most active transportation corridor in Napa County and also provides a major point of access between the rest of the Bay Area region and Napa County. 

Within American Canyon, Highway 29 also serves as the city's main thoroughfare and must provide access to places visited by local  residents and regional customers needing retail goods and services. Future development of transportation infrastructure in this corridor has a potential to provide even greater multi-modal access for thousands of local residents, daily commuters and millions of yearly visitors to Napa County. 

This corridor is the most rapidly changing area in Napa County and this project will energetically organize comprehensive community and stakeholder input to help plan most effective use of the existing and planned transportation system. The Plan will address context-sensitive design solutions for existing and planned arterials including SR29 and its connections to SR 37, SR 12, SR 121, SR 221 as well as potential expansions of parallel arterials in the City of American Canyon.
