This polygon datalayer contains MassDOT Highway sub-districts in the Commonwealth of Massachusetts. The sub-districts are sub-regions for each of the six highway districts. Their main purpose is to group highway maintenance teams for year-round state highway roadway maintenance.
The bounds of the districts were digitized from the MassGIS survey-level town boundaries. In addition to the polygon layer, there is an arc layer following the same line work as the polygon included in the downloadable shapefile.
This data is current as of September 2013.
