Jeremiah Morrow Bridge Replacement Project

Warren County, Ohio

 

Structures form Ohio's largest and tallest segmental bridge


•    Structure is Ohio’s largest, tallest segmental bridge
•    Smart design enhances construction safety, minimizes lifting and environmental impact
•    Durability reduces maintenance costs


HNTB was engineer-of-record and provided construction services for the Ohio Department of Transportation’s Jeremiah Morrow Bridge. The bridge that was replaced, two parallel continuous trusses on Interstate 71 north of Cincinnati, spanned a recreational area of the Little Miami River gorge. 

HNTB’s designed the replacement to be a variable-depth, six-span superstructure, which features cast-in-place, balanced cantilever segmental construction to enhance construction safety while minimizing lifting and environmental impact. 

The substructure consists of cast-in-place wall piers on footings supported on drilled shafts or driven steel piles. Smaller drilled shafts support abutments. Plus, the concrete box girder meets zero-tension design criteria for superior durability. Horizontal jacking balances the effects of creep, shrinkage and thermal shifts. Spare use of bearings and expansion joints reduces long-term maintenance costs.

At 2,252 feet long with main spans 239 feet above ground, the two structures form Ohio’s largest and tallest segmental bridge.
