The Maine Department of Transportation maintains a GIS map of all principle roads in the state: http://www.maine.gov/mdot/mapviewer/index.html
This map should be treated as the definitive source for all Federal Functional Classification of roads and, therefore, of their Waze road type. MaineDOT does not uniformly map roads that are not subject to state or federal funding, which detail should be developed from town maps, satellite imagery, and user reports.
