[1] Illinois 154 is the main east–west road through Pinckneyville.

Just before intersecting Interstate 57 on the eastern end, it bridges Rend Lake.

In 1937 it was extended west to Red Bud, replacing Illinois Route 170 and Illinois Route 13 in the process.

[3] In 1984, Illinois 154 was extended east on a new road over Rend Lake, replacing IL 183.

[2] The original 1926 routing of Illinois 183 is most likely underwater.
