History[edit]

SBI Route 123 was what Illinois 123 is now, plus a road from Ashland south to Alexander at Interstate 72/U.S. Route 36. In 1999, Illinois 123 was truncated on its southern end to Illinois 125. In October 2003, Illinois 123 was extended east to Williamsville, replacing some of Illinois Route 124 in the process as well as all of Sangamon County Route 11.[1]
