Seven winners have been named in Portland Cement Association’s (PCA) 13th Biennial Bridge Awards Competition. The competition, instituted in 1988, recognizes excellence in design and construction of concrete bridges. Roads and Bridges magazine was a co-sponsor.
The jurors honored the Mike O’Callaghan-Pat Tillman Memorial Bridge, spanning the Black Canyon between Arizona and Nevada, with special recognition as an outstanding achievement.
“The bridge designers have gone above and beyond to provide a beautifully engineered and constructed bridge. It stands in a class by itself.”
Winning projects were selected based on creativity, functionality, aesthetics, sustainability, and economy in design and construction by a jury of three prominent bridge professionals: Fred Gottemoeller, principal, Bridgescape LLC, Columbia, MD; Myint Lwin, director, Office of Bridge Technology, Federal Highway Administration, Washington, DC; and Malcolm Kerley, chief engineer, Virginia Department of Transportation.
Additional winning projects were:
- Delta Ponds Pedestrian Bridge — Eugene, Ore.;
- Bridge No. 207, Twyckenham Drive over St. Joseph River — South Bend, Ind.;
- U.S. 191 Colorado River Bridge — Moab, Utah;
- I-64 Kanawha River Bridge — Kanawaha County, W.Va.;
- South Maple Street Bridge — Enfield, Conn.; and
- Wapello County Bridge — Wapello County, Iowa
The 2012 program attracted 22 entries from Canada and the United States, covering a variety of structure types and construction methods. All structures were essentially completed between September 2009 and September 2011.
PCA will recognize the winners at the American Concrete Institute Fall 2012 Convention on Oct. 21 in Toronto, Ontario.
