Route 9 is a major east–west
state highway in
Massachusetts. Along with
U.S. Route 20,
Route 2, and
Interstate 90, Route 9 is one of the major east-west routes of Massachusetts, and like the others its eastern terminus is in
Boston. Starting at
Copley Square and passing along
Huntington Avenue, Route 9 is a limited access route through the
MetroWest suburbs to
Worcester, and is also a major alternative to the Pike's
toll road west of the city. After passing along major city streets in that city, the road becomes a country route, passing through the central Worcester Hills, the
Pioneer Valley, and the city of
Northampton, and into the
The Berkshires. The road ends near the center of the city of
Pittsfield.
