    The Iowa Department of Transportation offers no-cost, expert roundabout reviews during the feasibility, planning, design or operation of roundabouts in Iowa. The DOT is presently using a nationally-known and respected roundabout consulting firm to help ensure early success for roundabouts in Iowa, until such time that in-state experience and expertise are developed. Requests for services may be directed to Steven Schroder, PE, Iowa DOT's Office of Traffic and Safety at 515-239-1623 or Steven.Schroder@dot.iowa.gov or be accessed by contacting the district local systems engineer in your part of the state. The district local systems engineers are listed in the DOT's Need Answers publication.
