Jepson Parkway Project

The 12-mile Jepson Parkway project is an I-80 Reliever Route that will improve intra-county mobility for Solano County residents. The project upgrades a series of narrow local roads to provide a north-south travel route for residents as an alternative to I-80. The plan proposes a continuous four-lane roadway from the State Route 12 / Walters Road intersection in Suisun City to the I-80 / Leisure Town Road interchange in Vacaville. The project also includes safety improvements, such as the provision for medians, traffic signals, shoulders, and separate bike lanes.

The Jepson Parkway project is divided into 10 segments for design and construction purposes. Five (5) construction projects within the Jepson Parkway project have been completed: the extension of Leisure Town Road, from Alamo to Vanden; the relocation of the Vanden/Peabody intersection; improvements to Leisure Town Road bridges; the Walters Road Widening (Suisun City); and the I-80/Leisure Town Road Interchange (Vacaville).

The City of Vacaville, Public Works Engineering Services Division, has entered into a multi-agency agreement to perform design of the Leisure Town Road section of Jepson Parkway from Commerce Place to Vanden Road. Vacaville Engineering Services has also entered into an agreement to design the Solano County portion which runs south on Vanden Road from Leisure Town Road to the northern Fairfield City limit line.
