Stone Bridge spans the Conemaugh River in Johnstown , Pennsylvania . The bridge is a seven-arch stone railroad bridge located on the Norfolk Southern Railway mainline , built by the Pennsylvania Railroad in 1887-88 . Its upstream face was reinforced with concrete in 1929 . 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 . Scores of people were trapped and killed . The bridge is visible from Point Park in downtown Johnstown
