Construction of California High-Speed Rail
The construction of the California High-Speed Rail system is an undertaking by the California High-Speed Rail Authority. The project is expected to span about and will be completed in two phases: Phase 1 (totaling about ) runs from the metropolitan area of the San Francisco Bay Area in northern California to the metropolitan area of Greater Los Angeles in southern California. It has been under construction in the San Joaquin Valley since 2015, and in "bookend" investments in the two metropolitan areas, and will take an as-yet unknown number of years to complete. Phase 2 extends the system north to Sacramento, and south through the Inland Empire to San Diego. Funding for all of the Phase 1 construction has not been secured yet, and Phase 2 is only in the preliminary planning stage. Due to financial constraints, the Authority is implementing an Interim Initial Operating Segment (IOS) in the San Joaquin Valley (improving on existing Amtrak service). This will be a financially self-sustaining system. The next goal of the Authority is to extend the system west and north to San Francisco. Current construction status In the Central Valley major construction projects are underway. Three separate construction packages total 119 miles
