Jeremiah Morrow Bridge

Ohio’s tallest bridge spans the scenic Little Miami River.


The Jeremiah Morrow Bridge sits 239 feet above the Little Miami River and spans 2,252 feet in length. In June 2010, Kokosing was awarded an $88.1 million contract to replace the existing steel deck truss structures with cast-in-place, balanced cantilevered concrete segmental box girder bridges. The six-span superstructures sit on hollow-box monolithic piers and consist of single cell boxes varying in height from 10 feet to 19 feet. Kokosing’s custom-built forms advanced the piers while a custom modified form-traveler system serviced the superstructure.

This challenging project was driven by the linear schedule created from concrete strength and post-tensioning requirements. The first bridge was constructed between the existing I-71 northbound and southbound structures, allowing eight feet of clearance on each side. Access to the work was limited to a stair tower at each pier. The superstructure required a “balanced” installation by pouring the cantilever in 16-foot segments alternating each direction, casting a total of 244 segments between the two structures. The six year project duration involved installation of 49,000 cubic yards of concrete, ten million pounds of reinforcing steel and 3.2 million feet of post-tensioning strand.

The project was extremely successful due to the hard work and partnering between Kokosing, ODOT and their consultants.
