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.

Lock Levels

Wisconsin currently observes the following minimum lock levels for Waze road types:

Please note that there are current discussions for regional standards and these lock levels may change

 Freeway  - 5
 Major Highway  (MH) - 3
 Minor Highway  (mH) - 2
 Primary Street  (PS) - 2

The  Ramp  road type is to be locked at the level of road it serves.

i.e. a ramp connected to a Freeway is locked at 5, a ramp serving a Major Highway, multi-level intersection is locked at 3, etc.

All others - 1

Note: These are minimums and, for protection, certain segments may be at higher lock levels.

Name Normalization

Wisconsin will use the following standards for naming:
Freeways - I-###
US Highways - US-###
State Highways - WIS-###
County Highways - CH-XXX

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.
