Significance: The Coraopolis Bridge comprises two Pennsylvania through truss spans designed by Theodore Cooper and constructed in 1892 across the Allegheny River in Pittsburgh; in 1927, in an innovative demonstration of the adaptability of truss bridges, these spans were floated down river a distance of twelve miles and re-erected in combination with two pony truss spans. The bridge was listed on the National Register of Historic Places on January 7, 1986.
