The Johnstown Stone Bridge was built for the Pennsylvania Railroad. The May 31, 1889 floodwaters carried wreckage that collected at the bridge causing the flood waters to dam, sending a 40 foot wall of water back into the Kernville section of Johnstown. More than 100,000 tons of rock, locomotives, freight cars, the debris of homes and businesses, including many bodies–both living and dead collected at the bridge. A fire ensued killing many of the trapped people and hundreds of horses, donkeys, burros, and other animals. The inset photo is from July 10, 1889 when 450 pound charges of dynamite placed 30 feet apart finally opened the river channel.
