List of state highways in Vermont

The following is a list of state highways in Vermont as designated by the Vermont Agency of Transportation (VTrans). The classification of these state highways fall under three primary categories: Interstate Highways, U.S. Highways, and Vermont routes. Routes in Vermont are abbreviated as "VT #" by VTrans and also abbreviated as "VT Route #" and "Route #" in common usage. A small number of minor state highways, typically bypassing old alignments or short connector routes, are instead assigned names and unsigned four-digit numbers beginning with 9. Most state highways are maintained by VTrans; however, portions of some routes and some entire routes are maintained by local governments, such as towns or cities, instead. These town-maintained routes are internally called "state-designated town highways" and are typically designated as "class 2 town highways", or, in downtown areas "class 1 town highways". Many of Vermont's state-numbered highways retain their numbers from when they were part of the New England road marking system of the 1920s; for instance, VT 9 was part of Route 9 of the New England system.

Prior to 1995, Vermont used the standard circular highway shield to sign all of its routes, which had black numerals on a white circle over a black background. In 1995, Vermont introduced a new shield for state-maintained highways—a green shield with the word "Vermont" at the top. The circular highway shield continues to be used for locally maintained routes.
