1926 Arkansas state highway numbering

In 1926, the U.S. state of Arkansas renumbered its highways into a more traditional format. The system to be replaced was established in 1924 as Arkansas' first comprehensive highway plan. Roads were designated as "primary federal aid roads", "secondary federal aid roads", or "connecting state roads". The Arkansas State Highway Commission implemented the system of United States Numbered Highways also around 1926, and thus Arkansas decided to number its highways and to drop the 1924 letter-number format. This resulted in the first true numbering of state highways in Arkansas. The U.S. route designations 61, 63, 64, 65, 67, 70, 71,  165, and  167 would have conflicted with state highway designations, so there were no Arkansas state highways with these numbers. The highest number was 115, with 116 and up reserved for future use.
