    Iowa DOT's Traffic Engineering Assistance Program:

    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.

    See the Complimentary Roundabout Design Review Service brochure.
