American Canyon Commits Up to $5M to SR-29 Plan
The council backed NVTA’s $68 million corridor project and demanded the design keep room for a future pedestrian overpass.
AMERICAN CANYON: The American Canyon City Council has voted to support the Napa Valley Transportation Authority’s State Route 29 corridor improvement project, approving a commitment of up to $5 million toward design and right-of-way work.
The money is a multi-year pledge, not an immediate appropriation. It is split into $2 million for design and $3 million for right-of-way and utility relocation, with payments in tranches in 2027 and 2029, according to the council’s action.
NVTA engineering manager Grant Bailey presented the 1.3-mile plan, which carries a total delivery estimate of about $68 million, including roughly $53 million for construction. The design calls for adaptive traffic signals, transit priority for buses, dedicated Class I bike facilities, curb bulb-outs, median refuge islands and leading pedestrian intervals.
NVTA lists the project’s goals as improving corridor operations for all modes of travel, improving safety through Vision Zero approaches, cutting transit travel times, expanding multimodal options for pedestrians and cyclists, supporting growth in the city’s priority development areas and improving regional and local circulation. NVTA, Caltrans and the city hosted a public forum on the project on May 27, 2026.
The council amended its resolution to require that the project design not preclude future grade-separated pedestrian and bicycle crossings identified in the 2020 Congestion Management Corridor Plan, keeping the door open for an overpass even though none is in the current design.
The overpass debate
During public comment, resident Cindy Biederman urged the council to preserve a designated location or right of way for a future pedestrian and bicycle overpass, citing about 45,000 vehicles a day on Highway 29. Parents, school staff and transit riders told the council that signalized crossings alone may be inadequate to protect schoolchildren and disabled residents.
City Manager Jason Holly told the council the $5 million pledge could draw on traffic impact fees, of which about $5 million is on hand, and the general fund, depending on future revenue. The council adopted the resolution with the added crossing language by roll call.
NVTA’s preferred alternative, a signalized corridor with multimodal improvements at six intersections, was selected by the NVTA board and the council in February 2026. The roundabout alternative will not move forward. NVTA puts pre-construction costs at $20 million and construction at $55 million, with design and right-of-way work scheduled for 2027 and 2028 and construction in 2029 dependent on funding.
Public engagement will continue through a 30-day circulation period for environmental review and additional public meetings during design. Caltrans will own and operate the signalized facilities after construction.
