User:Emboar0413/1926 Indiana highway renumbering

In 1926, the U.S. state of Indiana implemented a complete renumbering of the state's highway system. All previous state highways were numbered, with the signage on all exiting roadways converting to the new numbering scheme on October 1. New additions to the state highway system were signed as they were completed, a task which was completed by 19XX. This was the second time Indiana state roads were renumbered, following a renumbering in 1923. The 1926 renumbering coincided with the establishment of the first thirteen U.S. Highways in the state- U.S. Route 12, U.S. 20, U.S. 24, U.S. 27, U.S. 30, U.S. 31, U.S. 36, U.S. 40, U.S. 41, U.S. 50, U.S. 52, U.S. 112, and U.S. 150.

The numbering system was changed in order to reflect the U.S. Numbered Highway System. As a result, state roads that received odd one-digit or two-digit designations are generally north–south highways, with odd road numbers increasing toward the west; state roads that received even one-digit or two-digit designations are generally east-west highways, with even road numbers increasing toward the south. A notable exception to this is State Road 67, a southwest-northeast route from Vincennes to Union City, which received this number because it was planned to become a part of U.S. Route 67, which ultimately never happened. Furthermore, state road numbers that conflicted with U.S. Highways in the state were removed.
