Fresno Trench & State Route 180 Passageway


The Fresno Trench is an approximately one mile long trench north of downtown Fresno that will carry high-speed trains under State Route 180, a rail spur, and an irrigation canal. The trench parallels Union Pacific freight tracks and includes an intrusion barrier wall to keep high-speed and Union Pacific trains separate. At its deepest point the trench will be about 40 feet below grade.


From approximately Olive Avenue to Stanislaus Street. Work on the trench has begun south of Belmont Avenue along with excavation beneath SR 180.


Ironworkers tie rebar in preparation for a concrete pour inside the State Route 180 trench north of downtown Fresno. The floor has been poured for the "box" that will carry high-speed trains under the highway, a rail spur and a canal. For the next step crews will pour the walls, while a little to the north inside the trench, other crews have been preparing the walls for rebar installation for the walls on that side.
