Jakway Park Bridge, Iowa, USA - Precast Elements


The project

The Jakway Park Bridge in Buchanan County is the first highway bridge in North America to be built with a new generation of Ductal® Ultra-High Performance Concrete (UHPC) pi-girders, the first North American highway bridge project to incorporate batching of Ductal® UHPC in a ready-mix truck, and the second highway bridge project in Iowa and North America built with UHPC girders, another significant step towards the FHWA's "Bridge of the Future".

The Office of Bridges and Structures at the Iowa Department of Transportation and the Bridge Engineering Center at Iowa State University designed the bridge a combination of cast-in-place, simple span slabs with a center span consisting of 3, 51-ft UHPC pi-shaped girders, produced by Lafarge Precast in Winnipeg, Manitoba, Canada.  Buchanan County, Iowa, was granted funding for this project through the TEA-21 Innovative Bridge Construction Program (IBRC), managed by the Federal Highway Administration (FHWA) to construct a highway bridge using an optimized pi-girder section with UHPC.


In 2009, this project won an Iowa Quality Initiative Structures Research Merit Award and a Precast/ Prestressed Concrete Institute (PCI) Design Award.
