This bridge held a record for a number of years after its completion for longest continuous truss bridge. It also has apparently held some sort of record for amount of weight it can hold, accounting for its massive members. Gustav Lindenthal, a noted engineer who designed such bridges as the Hell Gate Bridge in New York, was the engineer for this bridge as well. An important bridge company, the McClintic-Marshall Company was the contractor for the bridge. McClintic-Marshall built such bridges as the Ambassador Bridge.
The Sciotoville Railroad Bridge remains today an enormous feat of engineering, and it contains some of the most massive members and chords ever seen in a truss bridge. The bridge sits on concrete piers, and an extensive approach system is present for the bridge, including a deck truss span and numerous plate girder spans.
The Little Scioto River Railroad Bridge is nearby. An otherwise normal through truss span, it is dwarfed by the Sciotoville Railroad Bridge.
