The program, conducted by the National Steel Bridge Alliance (NSBA), honors outstanding and innovative steel bridges constructed in the United States. This year’s Prize Bridge Awards were presented April 18 at the 2012 World Steel Bridge Symposium (WSBS) and NASCC: The Steel Conference, a combined show in Dallas, TX.

(Editor’s note: Washington State DOT, which took this photo, says the worker is attached to appropriate fall protection, but the lines are difficult to see from this distance and angle.)|

Judges and Criteria
Selection of winning bridge projects was based on innovation, aesthetics and design and engineering solutions.
|More than 1,200 spectators watched as the Sam White Bridge was moved into place over five hours in March 2011— the longest two-span bridge ever moved by self-propelled modular transporters. The American Fork, UT, project earned a Commendation for its use of Accelerate Bridge Construction techniques.|
Judging was conducted by a jury of six bridge professionals:
• Benjamin Beerman, P.E., senior structural engineer, FHWA Resource Center, Atlanta;
• Robert Healy, P.E., director of structures, RK&K, Baltimore;
• David Hohmann, P.E., senior project manager, HDR Engineering, Austin, TX;
• Ray McCabe, P.E., senior vice president, HNTB Corporation, NY;
• Hormoz Seradj, P.E., steel bridge standards engineer, Oregon DOT; and
• Doug Waltemath, project manager, Harrington & Cortelyou, Kansas City, MO.
The winners were selected from nearly 70 entries covering a variety of structure types and construction methods. All structures were opened to traffic between May 1, 2009, and September 30, 2011.
