[edit] Exit list

Mileposts and exit numbers on I-70 begin at the Illinois-Missouri state line. As I-55 and I-70 overlap at the state line, they use the same numbering system until the I-55/70/270 interchange (exits 20A and 20B) where I-55 and I-70 split. At that point, I-70 mileage is based from I-270 at the Chain of Rocks bridge.
