Missouri Route 143


Route 143 is a short highway in southern Missouri. Its northern terminus is at Route 49 at Des Arc; its southern terminus is at Route 34 east of Piedmont.

History

Around 1934, a gravel road that extended several miles eastwards from Route 49 in Des Arc was designated as Route N. By 1937, another gravel road from Route 34 to Sam A. Baker State Park was constructed and designated as Route 101. Route N was extended to the Iron–Wayne county line by 1940. The road was renumbered to Route 143 by 1941, and the Route 101 designation was reused for another highway in Ozark and Howell counties. In late May of that year, a project to pave the entirety of Route 143 in oil aggregate treatment was announced. The work was completed by 1942. Route 143 was extended northwards further into the park by 1955, and Route N was paved in asphalt by 1958. A new gravel road, Route NN, connected Routes 143 and N by 1964. Route NN was paved by 1968, and Route 143 replaced Routes N and NN by 1970, with its northern terminus at Route 49.
