Highway Numbering

Vermont currently observes the following Standardized Name nomenclature for Numbered Routes:

Road Type Standardized Name
Freeway I-###
US Highway US-###
State Highway VT-###
Town Highway TH-###

State Highway numbering includes alternate state roads (e.g. VT-67A).

State Highway Signage

Most state highways are maintained by VTrans. However, some state highways in the centers of municipalities are maintained by local governments (class 1 town highways). VTrans maps indicate where state and local maintenance begin and end and signage may differ on municipally maintained segments. Map editors should treat both types the same.

Road Elevations

These are the general guidelines for elevation in Vermont.

  • Drivable and non-drivable segments are handled the same way with elevation.
  • Set elevation to Ground on all non-tunneled segments that are not passing over/beneath another segment or waterway.
  • Only segments that "cannot see the sky" should have negative elevation (i.e. tunnels).
  • Only set elevation as high as necessary.
  • Elevation of overlapping segments should be set relative to each other, with the lowest segment as Ground (unless a tunnel).
  • If you use the Bridge tool to join segments, be aware that it raises the elevation of the joined segment. Lower the joined segment as appropriate.

Regarding Local and Alternate Names:

In situations where a highway passes through a town, the road in those areas is typically named something other than the numbered route. In these situations the road should be named based on the following conditions:

  • If the local street signs provide guidance with the local name, that should be used as the primary name in the Waze map. The numbered route should be added as an alternate name.
  • If the local signs only indicate the route number, then that should be the primary name and the local road name should be added as an alternate name.


Locking roads

Vermont has adopted the New England Road Type Locking Standard.


Functional Classification

Functional Classification updates in Vermont have been completed. This will ensure a consistent, and better navigational experience to Wazers around the state and country. The general guidelines for implementation are in the Road types page. Any local deviations, and special information for Vermont will be listed below.

Resources

Vermont's Agency of transportation (VTRANS) has made a master Functional Classification map available online.

GIS Legend

The Vermont Classification and Color scheme comes from the official Functional Classification (FC) map that is published by VTRANS. The legend shows what classifications VTRANS uses and what color is assigned to each class.

VTrans to Waze Conversion Table

The numbers correspond to the FC type indicated on some VT maps. (e.g. Functional Class 7 road is a Major Collector)
