Avenue 15 Grade Separation

At Avenue 15, just east of Road 29 in Madera County, the western abutment construction for the Avenue 15 overpass continues. Dozens of shafts have been drilled, each one is three feet in diameter and 70 feet deep. The east side will have a cast-in-place wall on either side of the abutment, while the west side of the structure will have pre-cast Mechanically Stabilized Earth (MSE) wall panels to retain the fill on the abutment’s north and south sides. The piers for a supporting bent structure have been poured and next falsework will be erected to construct the bent cap. Eventually, concrete girders will link the abutments with the supporting bent to form the superstructure of the bridge.
