The Stone Bridge , located on the edge of Johnstown 's downtown , is an arched bridge built by the Pennsylvania Railroad in 1887 . On May 31 , 1889 , its seven arches blocked tons of debris , carried by the Johnstown Flood , including miles of barbed wire twisted through it from the destruction of a plant . The bridge withstood the force of the flood and this load . But an enormous fire broke out in the debris at the bridge , killing scores of people trapped within it , and burning for three days
