California High-Speed Rail Construction Package 4 | HNTB

High-speed rail in California will completely transform passenger rail in the United States. As the California High-Speed Rail program has reached a major milestone, HNTB experts are sharing their insights on this exciting project and the future of travel. The largest transportation infrastructure program currently underway in the United States, the California High-Speed Rail system will accelerate connectivity between the state’s mega-regions and serve as a testament to the power of high-speed systems. The first phase of the high-speed project will run from San Francisco to Los Angeles, by way of the Central Valley. Once operational, the passengers will be able to travel between San Francisco to Los Angeles in under three hours, a stark contrast to the typical 10 hours by way of car. With 119 miles of the California High-Speed Rail currently under active construction, the project is comprised of three Construction Packages. HNTB partnered with CAHSR as prime consultant and project construction manager on Construction Package 4 (CP 4). This segment is critical to the line’s overall success. It covers more than 22 miles and provides crucial rail guideway infrastructure that prepares the California High-Speed Rail Authority for the program’s next steps: track and systems installation.
