The California High-Speed Rail Authority’s Construction Package 1 (CP1) is the first significant construction contract executed on the Initial Operating Section of the High-Speed Rail project in California’s Central Valley. The CP1 construction area is a 32-mile stretch between Avenue 19 in Madera County to East American Avenue in Fresno County, including major work elements in downtown Fresno. It includes 12 roadway / railroad grade separations, two mainline viaducts, one tunnel, realignments of existing railroad tracks, utility relocations, roadway relocations, two trench sections, and a major river crossing over the San Joaquin River.

The CP1 design-build contract was awarded to Tutor Perini / Zachry / Parsons (TPZP), a Joint Venture, after an extensive, multi-year competitive bidding process.
