Oklahoma/Counties

Glossary

OKSL: Oklahoma Section Line Numbering. Beginning in the NW corner of the state, each section line is numbered, EW 1, NS 1. Many counties base county road numbering off of these numbers.

OKSL0: OKSL plus 0. i.e. EW 89 becomes 890. (examples used below: [NSEW] OKSL0 Rd = E 890 Rd). Some counties will omit the 4di number, causing NS 435 to become N 350 Rd and will be designated OKSL0-4.

[NSEW]: Single letter directional identifier (i.e. N or S or E or W). May omit W if there is never a West directional signed.

[NS/EW]: Two letter directional identifier (i.e. EW 43 or NS 120)
