National Steel Bridge Alliance


Prize Bridge Awards

The American Institute of Steel Construction and the National Steel Bridge Alliance are proud to announce the winners of the 2020 Prize Bridge Awards.

Since Pittsburgh’s Sixth Street Bridge won the first competition in 1928, more than 600 bridges of all sizes from all across the United States have received a Prize Bridge Award. Some of those bridges, such as the Wabash Railroad bridge in Wayne County, Mich., which won a prize in 1941 and still carries railroad traffic more than 70 years later, have actually outlasted the companies that built them.

“These projects are tributes to the creativity of the designers and the skills of the constructors who collaborated to make them reality,” said AISC President Charles J. Carter, SE, PE, PhD. “Steel shines and soars on their talents and we celebrate the accomplishments these projects represent.”

AISC and NSBA would like to thank the 2020 Prize Bridge Award judges for their time and enthusiasm:

  • Richard Marchione, deputy chief engineer (ret), New York Department of Transportation

  • Shane W.R. Kuhlman, state bridge engineer, New Mexico Department of Transportation Bridge Bureau

  • Frank Russo, vice president and technical director, bridge engineering, Michael Baker International

  • Rob Richardson, west region bridge leader, associate vice president, HDR

  • Dennis Golabek, GEC-FDOT Structures Design office, WSP

These dedicated judges considered every entry’s merits in terms of innovation, economics, aesthetics, design, and engineering solutions.

Judges weighed each project’s use of structural steel from both an architectural and structural engineering perspective, with an emphasis on creative solutions to the project's program requirements; applications of innovative design approaches in areas such as connections, gravity systems, lateral load resisting systems, fire and/or blast protection; aesthetic and visual impact of the project; innovative use of architecturally exposed structural steel (AESS); technical or architectural advances in the use of the steel; and/or the use of innovative design and construction methods.

The Prize Bridge Award program also recognizes the importance of teamwork, coordination, and collaboration in fostering successful projects. Awards for each winning project will be presented to the project team members involved in the design and construction of each winning bridge during an NSBA event in Branson, Mo. during the AASHTO CBS meeting, June 1 to 4.
