SOUTH NAPA COUNTY SR 29 Napa Valley is one of the most scenic areas in the San Francisco Bay Area. The Valley is a major tourist destination. It produces world-class wines in its 400+ wineries. It is also a world-class hospitality destination, hosting over 3 million visitors a year. Napa Valley’s growing economy is generating thousands of new jobs in manufacturing, agriculture, hospitality, construction, medical, and government. Napa’s cities and counties have worked diligently to conserve the Valley’s natural biodiversity by preserving open space and restoring bay wetlands, rivers, and creeks. The southern portion of the Valley is rapidly transitioning from rural to urban, creating new industry and housing in its southern most city, American Canyon. The rapid growth has created both challenges and opportunities. The main transportation artery in the Valley is California State Route 29 (SR 29), which traverses through Napa Valley from American Canyon to Calistoga, its northern most city. The City of American Canyon, incorporated in 1992, is one of the fastest growing cities in California. The rapid pace of the City’s housing and business development is placing substantial strain on the existing downtown infrastructure. The City is also isolated from the rest of the Valley because of the overstressed and limited highway, bike and pedestrian connections. To accommodate the growth, several SR 29 Corridor improvements are needed:
SOSCOL JUNCTION – Soscol Junction will alleviate congestion and improve operations at SR 29/221/ Soscol Ferry Road intersection in south Napa County. The preferred complete streets alternative is an elevated overpass with a free-flowing northsouth SR 29 and boasts two roundabouts north and south of SR 29 to facilitate turning movements on and off the highways. Cost: $64 Million
AIRPORT BOULEVARD – At the intersection of SR 29/12/Airport Boulevard, the project would add southbound queue jumps for express bus service; extend left-hand turn pockets in all directions, and free right-hand turning lanes. The project would include adaptive signals, linking North Kelly Road/ SR 12 and SR 12/Airport Boulevard. Cost: $5 MIllion
AMERICAN CANYON MULTIMODAL AND OPERATIONAL IMPROVEMENTS PHASE 1 – Bicycle, pedestrian and express bus transit improvements along the SR 29 corridor between Napa Junction and American Canyon Road. Phase 1 will also include operational improvements at key intersections. Cost: $28 Million
CARNEROS – At the intersection of SR 19/121/12, the project includes the channelization of northbound SR 29 lanes to be free flowing and free flowing right hand turn lanes on and off SR 12. Traffic from SR 12 eastbound turning onto to SR 29 would merge onto northbound SR 29 via a slip lane. Cost: $20 Million
