Interstate 57
Interstate Highway in Arkansas, Missouri and Illinois in the United States
Interstate 57 (I-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 east of I-55. The Interstate begins at I-40 in North Little Rock, Arkansas, traveling northward concurrently with U.S. Highway 67 (US 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 (Memphis, New Orleans, etc.) and Chicago, bypassing St. Louis, Missouri and Springfield, Illinois.
Between the junction of I-55 and I-57 in Sikeston and the junction of I-55 and I-90/I-94 in Chicago, I-55 travels for 436 miles (702 km), while the combination of I-57 and I-94 is only 396 miles (637 km) long between the same two points. In fact, both the control cities on the overhead signs and the destination mileage signs reference Memphis along southbound I-57, even as far north as its northern origin at I-94 in Chicago.
