Most states now publish bicycle maps that show traffic counts on many state roads as well as road configuration, the existence of paved shoulders, etc. I’ve found these maps to be of dubious value overall as often times there may be county roads that can better get you to your location. Fortunately, states like Illinois, Minnesota, Missouri and Wisconsin are now offering county maps that allow you to drill down and find lightly traveled roads that will take you just about anywhere you want to go.
Illinois – Illinois doesn’t have a downloadable PDF map, but you can order a paper copy. The good news is that this link does provide downloadable county maps.
Iowa – this link will get you a downloadable PDF file. There’s also a link if you want to order a free hard copy.
Iowa County Maps – I recently found this great resource of all the county maps in Iowa. I’ve downloaded these, so if the site goes away at some point, you can get these by emailing me.
Kansas – the Sunflower state has a colorful statewide downloadable map with city inserts.
Kansas County Maps – Statewide DOT maps for all Kansas counties that show road surfaces but not average traffic oounts.
Minnesota – this is an awesome resource from one of America’s best bicycling states. It includes not only a statewide map but county maps and a whole host of other tools.
Missouri – MoDOT offers statewide, regional and metropolitan maps.
Nebraska – Nebraska’s state map is big and colorful and includes inserts for most major cities.
South Dakota – South Dakota’s DOT provides two different maps, one that shows the type of road and the second that shows traffic counts. You can get both here.
Wisconsin – the land of cheese has the most comprehensive mapping resources of any state in the region. That’s not surprising as these folks were building bike trails like Elroy-Sparta back before it was cool.
