Conemaugh Viaduct
Posted September 26, 2016, by Nathan Holth (webmaster [at] historicbridges [dot] org)

This is the infamous bridge that held back the Great Flood of 1889 for seven minutes before failing, which actually made the flood worse because the "dam" formed by the bridge created a more powerful surge when it hit Johnstown.
