A little north of downtown Fresno, workers on the US 180 trench are excavating along the trench north of SR 180 which is being lowered another 10 feet to get to the “floor”, or invert, of the trench. Work has also begun on construction of the “floor” of the concrete box that will carry trains under the highway, a rail spur and the Dry Creek Canal. Rebar crews have started to tie rebar that extends up the sides of the trench for the walls. The trench will extend approximately 1 mile in length.
