Document Description
The Napa County Department of Public Works is proposing improvements to the State Route 12 and State Route 29 intersection in Napa County, California. The proposed project is located approximately six kilometers (km; 3.7 miles) south of Napa and approximately eight km (five miles) north of Vallejo, less than 1.6 km (one mile) west of American Canyon. The following improvements are proposed as part of the project. The construction of an additional northbound lane on Route 29 through the Route 12/29 intersection. This lane would be provided by widening the roadway into the existing unpaved median from 400 meters (1310 feet) south to 650 m (2130 feet) north of the intersection. Pavement widening would include one 3.6 m lane and one 0.8-m (2.6-foot) paved left shoulder. The extension of the two existing southbound left-turn lanes along Route 29 north of the intersection. These lanes would be extended by approximately 190 m (625 feet). The lanes would be 3.6 m (11.8 feet) in width and would include a 2.2m (7.0 foot) paved median. The relocation of existing traffic signals, electrical equipment, and signs in the median and outside of the existing shoulders to match the widened intersection. The addition of a second left turn lane from Airport Boulevard to Route 29 to provide additional capacity. The proposed project would be completed within state right-of-way. No additional right-of-way would be required.
