About the project

About the California High-Speed Rail Project: Construction Package 4 (CP-4)

Californians want a sustainable, innovative future, and high-speed rail is part of making that vision a reality. Construction Package 4 is the third design-build construction contract on the California High-Speed Rail Project. The project is located within the counties of Tulare and Kern, and the city of Wasco. It is bounded in the north by a point approximately one mile north of the Tulare-Kern County Line and terminates in the south at Poplar Avenue, just north of the city of Shafter. The project alignment extends 22 miles in length and will provide jobs and contract opportunities for approximately five years.

Construction will consist of at-grade, retained fill, and aerial rail sections. The project will relocate and re-purpose existing BNSF tracks and reconstruct selected roadways along with creating waterway and wildlife crossings. The project will consist of 14 structures- overpasses, underpasses, and viaducts; including a +2,000’ long pergola south of the city of Wasco. CP-4 is building the foundation for the future high-speed rail track and systems package.
