Location

The Stone Bridge spans the Conemaugh River in Johnstown, Pennsylvania. The bridge is a seven-arch stone railroad bridge located on the Norfolk Southern Railway's Pittsburgh Line, built by the Pennsylvania Railroad in 1887–88. Its upstream face was reinforced with concrete in 1929.^[1]

This bridge survived the Johnstown Flood of 1889, but the bridge blocked debris across the river. These materials, including barbed wire, subsequently caught fire and created an inferno covering 30 acres (120,000 m²). Scores of people were trapped and killed. The bridge is visible from Point Park in downtown Johnstown.

Stone Bridge c. 1905
