State routes in Maine are highways within the Maine State Highway System that are signed and maintained by the Maine Department of Transportation, and not U.S. Routes or routes of the Interstate Highway System. Some parts of these roads are maintained by local government authorities. There are over 100 State routes.
Note about termini: In several cases there is disagreement between the administrative termini of a route (which are defined by MaineDOT) and the termini signed in the field. All termini listed on this page are administrative termini; discrepancies are listed on the respective pages.
