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.

While in the State of Illinois, I-55 is multi-plexed several times.

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.

...Illinois State Route 3, at East St. Louis.
...Interstate 72, (Central Illinois Expressway) from the 6th Street Interchange on the south side of Springfield to Clear Lake Ave. on the east side.
...U.S. Rt. 36, (Central Illinois Expressway) from the 6th Street Interchange on the south side of Springfield to Clear Lake Ave. on the east side.
