Functional Classifications
Wisconsin follows the Functional Classification (FC) system for the USA.
To help update the current Wisconsin roadways to the new functional classifications, go to the Wisconsin Functional Classification Inventory.
Locking standard
The following defines a set of minimum locking standards proposed for all roads within Wisconsin. Any road of a certain type or category must be locked at least to the level in the chart below. Roads may be locked higher for protection and special situations (tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
It is understood that more rural or inactive areas may not yet meet this standard: editors are encouraged to recruit and mentor additional editors to build coverage.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US Road Type Standards.

Note: One-way PLRs used outside of parking lots, such as alleys and streets through apartment complexes, should be locked at 2. See the GLR major roads page for additional information on the standards listed here.
Name Normalization
Wisconsin will use the following standards for road naming:
Freeways - I-###
US Highways - US-###
State Highways - WIS-###
County Highways - CH-XXX
Forest Roads - FR-###
 |
There are no Township (Town) Roads in the state. All Town Roads are named, and those names will be used. The only exceptions would be if the road signage states differently. |
Additional notes for this state
- Dirt Roads - In Wisconsin all roads that are normally unpaved are considered dirt roads as this is how drivers expect the "Avoid Dirt Roads" feature to behave. Note that FC 'WILL' override a Dirt Road type.
- Toll Roads - There are currently no tolls in Wisconsin. No segments within the state of Wisconsin should be marked as 'Toll Road'
- Pedestrian Boardwalk and Walking Trail - These should not be mapped without approval from a State Manager for Wisconsin or the Regional Coordinator. These segment types can cause routing issues even when not connected to a driveable segment.
