The 2008 program attracted 42 entries from Canada and the United States, covering a variety of structure types and construction methods. All structures were completed between June 2006 and March 2008. The winners will be recognized at the American Concrete Institute's Fall Convention in St. Louis, in November.
Winning projects were selected based on creativity, functionality, and economy by a jury of three prominent bridge professionals: Edward Wasserman, civil engineering director, Structures, Tennessee Department of Transportation; Myint Lwin, director, Office of Bridge Technology, FHWA Washington, D.C.; and Barney Martin, Jr, president, Modjeski and Masters Inc.
