Missouri’s state highway system complements its Interstate and U.S. Highway corridors. Maintained by the Missouri Department of Transportation (MoDOT), numbered state routes and lettered supplemental routes connect cities, small towns, farms, and rural communities throughout the Show-Me State.
Missouri’s supplemental routes are particularly distinctive. Lettered highways such as Route D and Route JJ frequently provide local connections to larger roads, while numbered routes such as Route 5, Route 13, and Route 76 serve a variety of regional travel needs. Both systems are part of Missouri’s state-maintained road network; U.S. highways, including U.S. Route 36 across northern Missouri, carry a separate federal route designation.
From Ozark hills and winding valleys to broad northern farmland and the Mississippi River plain, Missouri’s routes offer a wide range of driving experiences. Open Road Archive documents these corridors with real driving videos through communities, countryside, and scenic regions across the state.
