Illinois highways

Illinois is the most populated of the Midwestern states and, because of its central location, is a hub for transportation.

The state has more primary interstates than any other state in the union, but we don't care about that, do we? Nope, let's stick to the slow lane.

Among the primary two-lane highways running through the state are U.S. 30 (Lincoln Highway), U.S. 40 (The National Road) and U.S. 50. And, of course, old Route 66, had its northern terminus at Chicago and ran south-southwest through Illinois to St. Louis.

Travel through the deep southern part of the state offers brilliant fall foliage scenery. Breathtaking views along the Mississippi River via the Great River Road and the Ohio River via the Ohio River Scenic Byway also beckon travelers.

Another scenic route to enjoy is the Illinois River Road in the north-central part of the state.
