They first printed them in 1924… and now they are printing them for just four cents more. At a cost of 19 cents a piece, The State Department of Transportation presents its 2007-2008 highway map for motorists and travelers. Director Pete Rahn says the maps are an important tool to help people navigate Missouri’s 32,000 miles of roads. The new map is 12% larger than previous maps. Rahn calls the maps “arguably the most popular publication from the state.” The maps are available to the public for free.
