There are no state or federal highways of any kind in the island counties, Nantucket or Dukes. There are eight mainland towns which have no state or federal highway routes: Mount Washington and Tyringham in Berkshire County, Hampden in Hampden County, Middlefield in Hampshire County, Leyden, Monroe and Rowe in Franklin County, and Nahant in Essex County. Other than Nahant, which is a peninsula town just south of the city of Lynn, the towns are mostly isolated rural communities in the western half of the state. Additionally, there are seven other towns which do not have any Massachusetts state highways: Chester, Holland, Mattapoisett, Montgomery, New Ashford, Shutesbury and Wilbraham. Wellfleet does not have any signed state highways but includes the silent concurrency of Route 6A with U.S. Route 6. Several other towns have less than a mile of state highway.
