Missouri Route 172

Route 172 in Lake Wappapello State Park

Route 172 begins at an intersection with U.S. Route 67 in the Mark Twain National Forest just south of Route 49. The route progresses eastward as a two lane highway through dense forests, soon weaving from northeast to the southeast. The highway crosses a power line cut and continues its gradual bends in different directions until becoming a steady northeastern road near an intersection with County Road 552, which heads southeast into the forest. The two highways parallel a distance apart, as Route 172 makes yet another dip to the southeast. After turning northeast, the right-of-way is taken over by Supplemental Route PP, where Route 172 turns to the southeast and enters a long clearing.[2]

In the clearing, the highway intersects with Supplemental Route W and the two roads become concurrent. For the mile-long concurrency, the surroundings remain dense forests until Route 172 forks eastward in a small clearing. The surroundings return to dense forests for Route 172, intersecting with an access road to Deer Run Acres and crossing into the outer edges of Lake Wappapello State Park. The designation terminates within the park, while the right-of-way continues towards Lake Wappapello.[2]

The entire route is in Wayne County.
