Missouri Route 33

Route 33 is a highway in western Missouri. Its northern terminus is at Route 6 in Maysville; its southern terminus is at U.S. Route 69 in Liberty.

Route 33 is one of the original 1922 state highways. Its northern terminus was at Route 8 (now U.S. Route 136) in southern DeKalb County. At Plattsburg, it turned west (modern Route 116) and then south on current U.S. Route 169.

A branch route, Route 33A, left the former alignment and connected it with Lathrop. This branch is now part of the highway itself.

Route 33 begins in the northeast corner of Liberty and travels 2 miles northeast before turning north and travelling another 3 miles to where it intersects Route 92 in Kearney. The road continues north, crosses under I-35 and continues north another 5 miles before turning east 1 mile and entering Holt. Leaving Holt, Route 33 enters Clinton County and heads northerly, passing Lake Arrowhead to the west and passing through Lathrop before reaching Route 116. Turning west and running concurrently with Route 116, Route 33 travels almost 5 miles before separating and turning north and running another 13 miles until reaching Route 36 in DeKalb County. Route 33 travels about 2.5 miles east concurrent with US-36 to Osborn, before turning north and traveling about 9 miles north until its northern terminus in Maysville.
