Construction Package 1 (CP1), a 32-mile stretch between Madera to Fresno, was the first significant construction contract executed for the CA High-Speed Rail Program. This package includes 12 grade separations, two viaducts, one tunnel, a major river crossing, and the realignment of State Route 99. JMA has completed the design of the three shooflies of the Union Pacific Railroad (UPRR) mainline in Fresno, including at: Downtown, Westside Wye and Herndon. These 3 shooflies, totaling over 14,000 feet of new track, enable the construction of five underpasses of UPRR required for establishing the high-speed train alignment adjacent to UPRR through Fresno. The work has involved substantial interface with UPRR design criteria and standards and engagement with UPRR staff and consultants to identify the specific constraints at each crossing and develop effective solutions to these constraints that meet UPRR criteria and construction phasing, staging and methods that minimize impacts to UPRR to the greatest extent possible. JMA prepared other elements of the design related to UPRR, including modifications to 3 temporary at-grade crossings and 2 permanent reconfigured crossings, and designed and coordinated numerous utility relocations and special protections required by the shooflies, for Kinder Morgan and PG&E facilities. The Downtown shoofly was completed in January 2022, the Westside Wye shoofly was completed in May 2022 and the shoofly for the Herndon Crossing was completed in May 2026.
