Interstate 57 is a north–south Interstate Highway that exists in two segments. It runs through Arkansas, Missouri, and Illinois. I-57 parallels the old Illinois Central Railroad for much of its route north of I-55. The Interstate begins at I-40 in North Little Rock, Arkansas, traveling northward concurrently with U.S. Highway 67 until it reaches Walnut Ridge, Arkansas, where the Interstate ends as of 2024. I-57 will run northward to meet up with the existing segment in southeastern Missouri. I-57 resumes its run from Sikeston, Missouri, at I-55 to Chicago, Illinois, at I-94. I-57 essentially serves as a shortcut route for travelers headed between the Southern United States and Chicago, bypassing St. Louis, Missouri, and Springfield, Illinois. From Wikipedia
