Interstate 57 (I-57) is an Interstate Highway in Missouri and Illinois that parallels the old Illinois Central rail line for much of its route. It goes from Sikeston, Missouri, at Interstate 55 to Chicago, Illinois, at Interstate 94. I-57 essentially serves as a shortcut route for travelers headed between the south (Memphis, New Orleans, etc.) and Chicago, bypassing St. Louis, Missouri. Between the junction of I-55 and I-57 in Sikeston, Missouri and the junction of I-55 and I-90/94 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, as well as destination mileage signs, reference Memphis along southbound I-57, even as far north as its northern origin at I-94 in Chicago. Likewise, at its southern end, Chicago is the control city listed for I-57 on signs on northbound I-55 south of Sikeston, Missouri, even though I-55 also goes to Chicago.

As of 2015^[update], I-57 has no spur routes, nor are any planned for the near future. At a length of just over 386 miles (621 km), it is the second longest two-digit Interstate Highway without an auxiliary route, behind I-49. I-57 has one business loop in Charleston, Missouri.
