Location

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.[10]
