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 2252feet long, 55feet wide, with 440feet 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. 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.[10]
