The Fresno–Bakersfield section forms part of the California High-Speed Rail (CAHSR) program, one of the largest high-speed rail infrastructure initiatives worldwide. The program comprises approximately 745.65 miles of high-speed rail network, connecting California’s main metropolitan areas, including Sacramento, the San Francisco Bay Area, the Central Valley, Los Angeles, Inland Empire, Orange County, and San Diego.

Currently under design and construction, the Fresno–Bakersfield section includes approximately 65.24 miles of high-speed rail platform, executed up to formation layer and protective asphalt layer, and designed for a projected speed of 250 mph. The alignment runs through California’s Central Valley, from the city of Fresno to a point located approximately 1 mile north of Kern County.

Key features of the project include two grade-separated crossings over the existing BNSF railway line, as well as several viaducts spanning major watercourses, including the Kings River, Cross Creek, Tule River, and Deer Creek, ensuring hydraulic continuity and seamless integration of the infrastructure within its surrounding environment.
