State Highways aka State Routes (SRs)

The current state highway numbering system was approved by the 1963 session of the state legislature and first posted in January 1964. The older primary and secondary state highway numbers remained as the official or legislative numbers until the 1970 session of the legislature made the newer posted numbers the official numbers. From 1964 to 1970 the posted route numbers were referred to as sign route numbers. Since 1970 they have been called state route numbers.
