Interstate 55

A north-south interstate, I-55 cuts across the state in a diagonal from Illinois/Missouri State Line, at St. Louis to Plainfield, IL. At Plainfield, the road turns more east-west and ends at Lake Shore Drive, just south of Downtown Chicago. I-55 is what replaced much of Historical U.S. Rt. 66 through this state. Portions of I-55 today use streches of the old highway.

I-55 is multiplexed with...
...Interstate 64, from the Poplar Street Bridge at St. Louis, MO for Aprox. 1 mile.
...Interstate 70, from the East St. Louis to Troy, IL.

...U.S. Rt. 40, from the Poplar Street Bridge at St. Louis, MO to just South of Troy, IL.
