History
Initially, US 36 followed part of IL 106, IL 36, IL 3, IL 10, and IL 121 (which is newly built back then). A couple of portions were under construction. In 1935, these state routes were either truncated or removed due to confusion (like IL 36) and redundancy. In 1936, US 36 moved from the
Wabash Bridge (now used by railroad) to the
old Mark Twain Memorial Bridge.
From 1942 to 1971, US 54 ran concurrently with US 36 from New Hartford to Chicago via US 36 and several other routes.
Until around 1977, no significant changes to US 36 were made. Then, Interstate 72 (and another part of the freeway that would later become I-72) extended from Monticello to Jacksonville. As a result, US 36 moved to a part of I-72 from Decatur to Jacksonville. By 1979, the freeway then extended west near Riggston. By 1988, it extended west to IL 100. At this point, the
Valley City Eagle Bridges were completed. However, by 1992, the twin spans, as well as the freeway west to IL 336, opened. By 1996, the Interstate 72 designation extends west using the new US 36 freeway and ends abruptly as soon as US 36 leaves the freeway. Also, Interstate 172 acquired the whole of the IL 336
freeway portion. In 2000, I-72 extended west to connect to Hannibal, Missouri, after a new

opened. As a result, US 36 moved northward to get onto the new bridge. After that, the old bridge was demolished.
