The Jeremiah Morrow Bridge is the name for a pair of concrete box girder bridges built between 2010 and 2016 [2] which carry Interstate 71 over the Little Miami River gorge between Fort Ancient and Oregonia, Ohio. The bridges are named for former Governor of Ohio Jeremiah Morrow. [5]

The bridges are 239 feet (73 m) above the river, making them the highest bridges in Ohio, [6] and are 2,252 ft (686 m) long, 55 ft (17 m) wide, with 440 ft (130 m) main spans. [1] The bridges each have two marked lanes with room for a third lane. [2]
The original Warren truss bridges [7] at the same location were opened to traffic in 1965 [4] and were continuous across five spans. [8] Both of the original spans were replaced beginning in 2010, with the completion of construction work marked with an official ribbon cutting ceremony held on November 18, 2016. [2] [4]
The original bridges were approximately the same design and age as the I-35W Mississippi River bridge which collapsed in 2007. [7] Demolition of the original southbound bridge was largely completed on April 23, 2017. [9] The original northbound bridge had been demolished in 2014 after one of the new bridges was complete.
