Local Agency Bridge Innovation and Demonstration Days
The Iowa Local Technical Assistance Program (LTAP), along with the Buchanan County Secondary Roads Department, with funding from the Iowa Department of Transportation (DOT) and the Federal Highway Administration (FHWA) regularly host a free Local Agency Bridge Innovation and Demonstration Days event.
Local agency representatives and others from throughout Iowa and surrounding states are invited to attend this event. The tentative agenda each year typically includes national/state perspectives, research discussions, and local agency implementation experiences with a wide variety of efforts. It also includes a tour of the bridge innovations that have been applied throughout the hosting community.
