One of the items MoDOT produces for public information is a map detailing the amount of traffic using the state system of roads.  Due to the size of Missouri's system of state roads, the seventh largest in the nation at more than 32,000 miles, the department typically produces these maps on a three-year cycle.   A statewide map and versions for each of our 10 districts are available. If you have trouble downloading any of the files or would like a paper copy of one or more of these maps mailed to you, please go to our Request More Information section for and fill out a request form.
