Title: Jameson Canyon Project
Description: Caltrans and FHWA propose to improve operations between SR 29 and I-80 with improvements along SR 12. SR 12, also known as Jameson Canyon Highway, serves as a major inter-regional east-west link between southern Napa Valley and the Fairfield / Suisun Valley areas in the North Bay. The two-lane conventional highway is used for commercial, agricultural, commuter, and recreational traffic on a regular basis. With the objective of reducing capacity constraints, improving safety conditions and enhancing operational efficiency in the area, the project would incorporate the following major components: 1) Widen a 9.5 km (5.9 mile) stretch of SR 12 from two to four lanes between Kilometer Post ("KP") 0.0-5.3 (Post Mile [PM] 0.0-3.3) in Napa County and KP 0.0-R4.2 (PM 0.0-R2.6) in Solano County; 2) Upgrade SR 12/29 intersection to an interchange, located in Napa County; and 3) Upgrade Red Top Road/SR 12 intersection to an interchange at KP R3.9 (PM R2.4) in Solano County.
