[edit] History

Interstate 55 was built in sections across Illinois between 1960 and the late 1970s. This expressway largely replaced former Route 66 in Illinois, and some stretches directly overlap the old highway. One can find many signs posted noting the historic route. The earliest stretches were built near Chicago along the Southwest Expressway (later renamed the Stevenson Expressway), with later portions being built downstate.

[edit] Future

In northeastern Illinois near Joliet, I-55 is being widened from two to three lanes in each direction between I-80 (exit 250) and Weber Road (exit 263). Preliminary bridge work for this project was completed in 2007, with mainline work to be done in 2008.

[edit] Exit list

Mileposts and exit numbers on I-55 begin at the Illinois-Missouri state line. As I-55 and I-70 are multiplexed at the state line, they use the same numbering system until the 55/70/270 interchange (exits 20A and 20B) where I-55 and I-70 split.
