Summary
Significance: This structure is the first large stone arch bridge among many that defined Chief Engineer William H. Brown's reputation as the Pennsylvania Railroad's "stone man." The site is also significant as the location of a predecessor structure, the railroad's first all-iron truss bridge. The so-called "Stone Bridge" played a prominent and tragic role in the Johnstown Flood of 1889.
