As of 2018, trains like the City of New Orleans[1] travel over the Ohio River supported by the same piers whose construction began in 1887.Despite increased precautions following the deaths, a total of five men died of decompression sickness during construction.In order to comply with regulations meant to allow steam boat travel on the Ohio, the bridge was required to be 53 feet (16 m) above the river's high-water mark.This resulted in the structure extending nearly 250 feet (76 m) from the bottom of the deepest foundation to the top of the highest iron work.On October 31, 1895, a magnitude 6.6 earthquake on the New Madrid Seismic Zone with an epicenter at Charleston, Missouri, cracked a pier on the bridge.
