June 16, 2025

WHAT YOU NEED TO KNOW: The Avenue 56 grade separation is the first high-speed rail structure to be completed in Tulare County. Previously impacted by the 2023 floods, the overpass is now open to traffic spanning 219 feet long, taking traffic over the future high-speed rail tracks.
TULARE COUNTY, Calif. –  The California High-Speed Rail Authority (Authority) today announced that the Avenue 56 grade separation is completed and now open to traffic. It is the first completed high-speed rail structure in Tulare County and the 55th structure completed for the system.

The Avenue 56 overpass was one of several high-speed rail structures impacted by atmospheric rivers and heavy rains that hit Kings and Tulare counties in March 2023. To assist and help the surrounding communities, the Authority worked with emergency personnel and Tulare County to build up berms to divert water and prevent flooding in the area, and for community members to utilize as an emergency access road. The berms were also used by local farmers to help transport livestock out of the flooded areas. More than 114,000 cubic yards of dirt was transported from Avenue 56 to build up the elevated berms.

“To ensure the surrounding communities were safe and had access to vacate if needed during the heavy rains in 2023, the Authority and our contractor worked cooperatively with local agencies and emergency services. We are delivering the nation’s first high-speed rail system and there are opportunities during construction to also help address the needs of the local community."

Garth Fernandez, Authority Central Valley Regional Director
The Avenue 56 overpass will serve as a grade separation, taking traffic over the future high-speed rail tracks. Located south of the city of Corcoran, the structure spans more than 219 feet long, and 35 feet wide. The structure is comprised of 12 pre-cast concrete girders, 850 cubic yards of concrete and 161,795 pounds of steel.

Construction progresses every day on the California high-speed rail project. In addition to continued progress across the Central Valley, the Authority also announced the completion of four grade separations at Fargo Avenue and Whitley Avenue in Kings County, and at Belmont Avenue and Central Avenue in Fresno County.
