THE BRIDGE OF THE FUTURE
The first Ductal/UHPFRC (Ultra-High Performance, Fiber-Reinforced Concrete) highway bridge in North America, the Wapello County Mars Hill Bridge in Iowa, won the 2006 Portland Cement Association Bridge Award from among 78 entries from Canada and the United States, covering a variety of structure types and construction methods.
After 5 years of collaboration by the U.S. Federal Highway Administration (FHWA), the Iowa Department of Transportation, Iowa State University/Bridge Engineering Center and Lafarge North America, this innovative bridge provides a significant step towards “The Bridge of the Future.” With a single-span, 3-beam cross section, it has three 110-foot Ductal girders with no rebar for shear stirrups. The unique girders were produced by Lafarge AC Precast in Winnipeg, Manitoba and delivered to the site in Iowa.
Constructed under the Innovative Bridge Construction Program, it is part of the FHWA “Bridge of the Future Program.”
