Relocation of State Route 99

Portions of State Route 99 (SR 99) located within the CP 1 contract limits will be realigned to accommodate the high-speed rail project between the existing SR 99 and the Union Pacific Railroad. Additionally, the project will improve traffic operations, reduce congestion, and enhance traffic safety in the region. In January 2013, the High-Speed Rail Authority signed an agreement with the California Department of Transportation (Caltrans) to complete the realignment process.
