Interstate 49 is a north–south Interstate Highway that exists in multiple segments: the original portion entirely within the state of Louisiana with an additional signed portion extending from I-220 in Shreveport to the Arkansas state line, three newer sections in Arkansas, and a new section that opened in Missouri. Its southern terminus is in Lafayette, Louisiana, at I-10 while its northern terminus is in Kansas City, Missouri, at I-435 and I-470. Portions of the remaining roadway in Louisiana, Arkansas, and Texas, which will link Kansas City with New Orleans, are in various stages of planning or construction.
Although not part of the original 1957 Interstate Highway plan, residents of Missouri, Arkansas, and Louisiana began campaigning for the highway in 1965. When I-49 is complete, the goal of the association will have been accomplished, with only a brief gap (served by other Interstates or US 71) and route number change in Kansas City.
