BuildHSR: High-Speed Rail Projects
McKinley Avenue Grade Separation Groundbreaking
On December 10, 2024, the California High-Speed Rail Authority broke ground on the McKinley Avenue and Golden State Boulevard Grade Separation. The project is located between State Route 99 and West Avenue in Fresno. The overpass will span 402 feet long and be more than 78 feet wide. The grade separation will serve as a four-lane roadway. When complete, the grade separation will improve safety for drivers, bicyclists and residents near the future high-speed rail tracks and existing railroad tracks.
