SUDAS (pronounced “soo’dahs”) is short for Statewide Urban Design and Specifications. The Institute for Transportation at Iowa State University maintains Iowa’s SUDAS manuals for public improvements. Developing and maintaining Iowa’s unique SUDAS manuals is the result of a lengthy and painstaking effort by more than 300 stakeholders across the state.
