of Portageville, the road meets I-55 at a diamond interchange, and US 61 continues its concurrency with I-55. Route 162 continues eastward through rural New Madrid County. East of CRD 427, the road intersects the termini of Routes KK and TT. At Route M, Route 162 begins travelling southwestwards toward the Mississippi River. CRD 439 is the last intersection before the road ends at a boat ramp near the river. History Around 1932, Routes C and K were designated along gravel roads in the Missouri Bootheel. Route C connected from Route 25 in Clarkton to Gideon, while Route K was from Portageville to near the Mississippi River. Route K was extended southeastward one year later, intersecting the newly designated Route M. Route C was extended east of Gideon in 1935, and its section from Clarkton to Gideon was paved one year later. The section of Route C east of Gideon was paved by 1949, and the route was extended eastward by 1953. Route K was also paved during that time. By 1954, Route C was extended along a gravel road to Portageville, connecting with US 61 and Route K. In 1956, Route 162 was designated, replacing Routes C and K. The remaining gravel section and was paved that year. An interchange at I-55 was being built during 1967, and it was completed later that year. The project was part of the I-55 extension from New Madrid to Portageville, with a total cost of $6,375,556 in 1966.
