AISC/NSBA Recognizes Exemplary Steel Bridges for More than 90 Years

First Place—1928 Award 
Sixth Street Bridge, Pittsburgh, Pa.; Engineer, V.R. Covell, Chief Engineer of Bridges; Fabricator, American Bridge Co.; Owner, Allegheny County; Completed in 1928; Span length: main span, 442 ft., 1 in.; 2 side spans of 221 ft. 

Launched in 1928, AISC's Prize Bridge Awards competition was established to recognize and showcase the beauty of steel bridges across America.

The historic first award went to the Sixth Street Bridge in Pittsburgh, as it embodied innovation in the steel bridge industry at the time. It was one of the first self-anchoring suspension bridges and used solid steel eye-bars for both the main suspension cables and the vertical support for the deck. Now more than 90 years old, the Sixth Street Bridge—renamed the Roberto Clemente Bridge in 1998 after Pittsburgh Pirates Hall of Fame outfielder Roberto Clemente—has come to define a city and its history.

More than 600 bridges of all sizes from across the U.S. have been recognized and honored through this awards program since 1928. Now administered by NSBA, AISC's bridge division, today's Prize Bridge Award winners receive national acclaim with recognition during NASCC: The Steel Conference and the World Steel Bridge Symposium. The winning projects are also featured in Modern Steel Construction and are showcased on the AISC website.
