Illinois Interstate Highways
Illinois's Interstate Highways connect its major cities and facilitate travel between Illinois and its neighboring states. I-39 links I-90 near Rockford in northern Illinois with I-55 and I-74 in central Illinois. I-55 extends southwest from Chicago toward Saint Louis, and I-57 extends from Chicago to the south. I-64 passes through southern Illinois between the Indiana border and the Missouri border at Saint Louis. I-70 crosses south central Illinois from east to west; I-74 traverses north central Illinois; and I-80 crosses northern Illinois from east to west, passing through the Chicago metro area. I-88 (a toll road) extends from Chicago to the west. I-90 enters Illinois at the Wisconsin border, passes through Chicago, and leaves Illinois at the Indiana border. In Illinois, I-94 generally skirts the Lake Michigan shoreline, although the highway runs a bit inland to serve the south side of Chicago.
Illinois's auxiliary Interstate Highways serve more localized areas such as metropolitan Chicago and Peoria.
- I-155 connects I-55 near Lincoln with I-74 near Peoria.
- I-180 connects I-80 near Princeton with the Illinois River region north of Peoria.
- I-190 connects Chicago O'Hare International Airport with I-90 northwest of Chicago.
- I-255 forms the eastern side of the highway loop around Saint Louis, providing access to East Saint Louis and adjoining areas.
- I-280 skirts southern Moline and Rock Island, providing an alternate route to I-80 in western Illinois.
- I-290 runs west from downtown Chicago, then northwest from I-294 to its terminus at I-90.
- I-294 is a toll road that loops through the inner Chicago suburbs.
- I-355 is an outer loop toll road that runs through outlying Chicago suburbs.
- I-474 provides an alternate route to I-74, through Bartonville and the southwestern outskirts of Peoria.
Illinois Scenic Routes
Meandering through southern Illinois, the Shawnee Hills Scenic Byway passes through picturesque farmlands and breathtaking wilderness. Traveling south from Harrisburg to Herod, visitors will encounter the Shawnee National Forest and an odd formation of sandstone rocks known as Garden of the Gods. Farther south lie Cave-in-Rock State Park, Elizabethtown, and the Illinois Iron Furnace, as well as the town of Golconda, which boasts a rich history of commerce along the Ohio River. More information about scenic roads in Illinois is available on this Illinois Byways site.
