Stanley Ave. Bridge Replacement I-75

The $14.8-million project called for the removal and reconstruction of a five-span, 578-foot-long, twin-concrete beam structure over The Great Miami River in Dayton. The bridge’s substructure consists of 363, HP14x73 steel piles – ranging from 25 feet to 50 feet in length; the total quantity of the structure’s pile length is 11,970 linear feet (lf). More piling is found adjacent the bridge in two cast-in-place retaining walls, which features a total of 7,330 lf of HP10x42 pile ranging from 55 to 70 feet in length.

The project site’s hard sub-surface conditions resulted in Kokosing pre-boring several of the holes for H-piling installation. This was accomplished by our own forces using Kokosing’s track hoe-mounted Watson drill. Kokosing self-performed all of the project’s piling work with its fleet of cranes, diesel, air-impact and vibratory pile hammers and track hoe-mounted sheet pile installers.

Kokosing also installed and removed on the project more than 50,000 square feet of sheet piling cofferdams, which were designed in-house.
