History
U.S. Route 124
U.S. Route 124 (US 124) was a U.S. Highway that was commissioned from 1926 to 1938, and was located in Illinois, traveling from Peoria through Biggsville. It was approximately 80 miles (130 km) in length, and followed much of the route of IL 116, prior to its decommissioning. SBI Route 116 originally traveled separately from east of Ashkum to East Peoria.
US 124 was an original 1928 US route in Illinois, since before then US routes didn't appear on Illinois maps.

Why this record matters
The phrase “east-west state highway in Illinois, US” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q1035085. Authority coordinates are 40.775, -89.428. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1926, 1938 and 1928.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
