Missouri Route 5 is the longest state highway in Missouri and the only Missouri state highway to traverse the entire state. To the north, it continues into Iowa as Iowa Highway 5 and to the south it enters Arkansas as Arkansas Highway 5 as part of a three state 650 mile highway 5. With only a few exceptions, it is mostly a two-lane for its entire length.^[2]
