The original 1833 single-arch Conemaugh Viaduct was destroyed in the Johnstown Flood of 1889. During the flood, debris built up behind the viaduct, holding back the water. When the viaduct suddenly failed, the water was released in a powerful burst that destroyed the nearby town of Mineral Point, and then Johnstown itself. This double-arched replacement was built in the 1890s to replace the destroyed viaduct, and today it carries Norfolk Southern's Pittsburgh Line, the successor to the Pennsylvania Railroad Main Line.
