New $88M Jeremiah Morrow Bridge to Improve Safety By Brenda Ruggiero CEG CORRESPONDENT
Only minor work remains to complete an $88 million project on the Jeremiah Morrow Bridge in Warren County, Ohio. A ribboncutting ceremony was held on Nov. 18, to commemorate the completion of the project’s major workload. “The new structures will help to keep people safe and commerce moving in Ohio,” said Jerry Wray Ohio Department of Transportation (ODOT) director. “They will serve the people for several decades.” The new Jeremiah Morrow structures are among Ohio’s longest bridges, spanning nearly 2,300 ft. (701 m), and also are the state’s tallest at 239 ft. (72 m) above the Little Miami River. The main spans will be 440 ft. (134 m) wide, and will carry more than 40,000 vehicles daily on Interstate 71. “The completion of this project will have an enormous benefit to Ohio,” said Tammy Campbell, ODOT District 8 deputy director. “Pulling this project together was an enormous undertaking and its efficient completion is a tribute to our project team.” The new bridges will carry two lanes in each direction across the Little Miami Valley, but reportedly have room to add a third lane in the future. Construction on the project began in August, 2010. The project is located between Columbus and Cincinnati and replaces the high level bridges on Interstate 71 just outside Wilmington. The existing deck truss bridges were replaced with a concrete cast-in-place segmental

box structure using the balanced cantilever method of construction. The twin spans are named after Jeremiah Morrow, who served as a state senator, Ohio’s first U.S. representative, a U.S. senator, and an Ohio governor between 1803 and 1842. Omnipro Services is providing comprehensive construction support and construction site services
for ODOT for the project. The northbound replacement span opened to traffic on Nov. 20, 2013. This first phase took three years to complete. The new bridge is reportedly designed for so-called super loads, unlike the old structure. HNTB is the engineer-ofrecord, providing construction services for ODOT. The bridge
design features cast-in-place, unbalanced 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, and 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 reportedly reduces long-term maintenance costs. Kokosing was awarded the project to reconstruct the Jeremiah Morrow Bridge in June of 2010. see BRIDGE page 2
