In 1926 and 1927, Missouri implemented a major renumbering of its state highways because of the implementation of the US Highway System. Routes 2, 3, 7, 8, 9, 11, 12, 14, and 23 were entirely replaced by U.S. Routes. Routes 36, 40, 50, 60, 61, 62, 63, 65, 67, and 69 conflicted with new designations (note that Route 71, another conflicting number, had already been replaced by Route 3 by then because the portion of Route 3 here was not built), so the routes with these numbers had been renumbered. Note that a route number wasn't decided for renumbering State Route 65 (which was just removed from the state highway system temporarily) until 1927. 
In 1927, additional renumberings took place, as what was planned as US 62 became US 60, what was planned as US 60 became US 66, and US 54, which was mistakenly omitted from the list, was added, and extended further east from its originally planned east end; new State Routes 26 and 62 was created, State Routes 26 and 54 were renumbered, State Route 66 (another conflictive number) was replaced by US 54, and a route number was decided for renumbering the road that was Route 65 before 1926, eliminating the old route with that number and consolidating it with another route:
|U.S. Route 60||U.S. Route 66||Kansas||Illinois|
|U.S. Route 62||U.S. Route 60||Springfield||Kentucky|
|Route 15||U.S. Route 54||Buffalo||Mexico|
|Route 15||Route 15||Mexico||Iowa|
|Route 22||Route 22||Clark||Mexico|
|Route 22||U.S. Route 54||Mexico||Illinois|
|Route 26||U.S. Route 54||Kansas||Eldorado Springs|
|Route 26||Route 62||Eldorado Springs||Osceola|
|Route 32||Route 32||Licking||Flat River (32 overlaps US 61 to Farmington)|
|Route 54||Route 26||Paris||New London|
|Route 66||U.S. Route 54||Eldorado Springs||Buffalo|
|Route 68||Route 32||Farmington (32 overlaps US 61 to Flat River)||Sainte Genevieve|
|N/A (this was 65 before 1926)||Route 68||St. James||Vichy|
