Fresno Trench & State Route 180 Passageway

Workers continue excavating the crossing under State Route 180 (SR 180) outside of downtown Fresno. As they dig down five feet, they add to the retaining wall with a rebar mesh and sprayed concrete, known as shotcrete. There’s about 18 feet left to excavate before crews will construct a concrete box that will carry the trains under SR 180, a rail spur and the Dry Creek Canal. At the trench, to the north of the SR 180, additional precast struts have been set, approximately 800 feet have been partially excavated. Crews are installing temporary supports to excavate the remainder in this area of the trench. Ultimately, the trench will extend approximately one mile in length.
