The Wisconsin Transportation Library collects reports, statistics, photographs, pamphlets, brochures, and maps relating to the work of the Wisconsin Department of Transportation and other organizations studying transportation in the state. Some of the topics covered include roads and highways, bridges, rail, bicycling and pedestrians, aeronautics, scenic byways, transit, environment, safety, law enforcement, freight, and transportation planning. Together these documents reflect current practice and research, and Wisconsin transportation history.
