Interstate 49 (I-49) is a north–south Interstate Highway with multiple segments. The original portion is entirely within Louisiana with an additional signed portion extending from I-220 in Shreveport to the Arkansas state line, three newer sections are in Arkansas, and one section 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. Future plans include portions of the remaining roadway in Louisiana, Arkansas, and Texas, to link Kansas City, Missouri with New Orleans.
