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 directions if never signed (NSE omits W if there is never a West directional signed.)

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

[ord]: Ordinal (the 'st', 'nd', 'rd', or 'th' that follows a number)

FC: Functional Classification

Common Questions Regarding County Naming/Functional Classification

Q: A county road that is dirt is marked primary. Which do I use, Dirt Road or Primary?
A: Primary. Be sure to mark the road as Unpaved as well to prevent routing to those that don't wish to be routed down an unpaved road.

Q: I believe a road should be higher than the Functional Classification. Can I raise it?
A: Yes, please send a PM/Slack DM to a State Manager to let them know. If we were to see it higher without explanation, we may change it back.

Q: I believe a road should be lower than its Functional Classification. Can I lower it?
A: No. This is per the US Functional Classification policy. Lowering a FC requires approval from a RC. Should you feel it has a valid case, please submit a permalink to a state manager.
