The Office of Transportation Planning's Geospatial Resources section maintains many transportation related GIS layers, for use in transportation planning. Layers include road, rail, sea, and air transportation modes within Massachusetts. In addition, transportation agency jurisdictional boundaries are available.

All of the GIS layers are stored in NAD 1983 Massachusetts Mainland State Plane Coordinates - Meters. All downloadable files are available in ESRI geodatabase format to preserve the full names for each attribute. Shapefiles can be provided upon request. The boundary layer geodatabases contain both the polygon and arc versions for your convenience.
