About the research

The Iowa Department of Transportation has received funding for an Accelerated Innovation Deployment (AID) project from the Federal Highway Administration to construct bridges using box beams made with ultra-high performance concrete (UHPC). Through the use of this approach to accelerated bridge construction (ABC), the duration of off-site detours during the course of a project will be reduced. The reduced construction timeline is expected to translate into improved safety for the traveling public, as the shortened duration of off-site detour routes would reduce exposure and the potential for crashes to occur along those routes.
