Massachusetts Route 2

Massachusetts Route 2 is a major east–west state highway spanning the northern tier of the Commonwealth of Massachusetts. It connects the Berkshires in the west to the Greater Boston metropolitan area in the east, serving as a vital corridor through the Pioneer Valley and North County region. The route is famously known as the Mohawk Trail for its scenic western segment through the Hoosac Range and the Deerfield River valley. Its eastern terminus is in Cambridge near Alewife station, while it continues west to the New York border at Williamstown.

Route description

Beginning at the New York State Route 2 border crossing in Williamstown, the route traverses the scenic Berkshires, officially designated as the Mohawk Trail west of Millers Falls. This segment features notable landmarks like the Hail to the Sunrise statue and the Mohawk Trail State Forest. It passes through towns such as North Adams, Charlemont, and Greenfield, following the Deerfield River for a portion. East of Orange, the highway becomes a controlled-access expressway, known as the Route 2 freeway, bypassing Gardner and Fitchburg before transitioning back to a surface road in Concord. The final urban segment passes through Lincoln, Lexington, and Arlington before terminating at Alewife Brook Parkway in Cambridge.

History

The western alignment follows the historic Mohawk Trail, an ancient Native American path later used by European settlers. The state began improving the roadway in the early 20th century, with the famous Mohawk Trail "hairpin turn" near Florida constructed in 1914. The eastern expressway portion was developed incrementally throughout the mid-20th century to alleviate congestion, with key sections opening in the 1950s and 1960s around Acton and Littleton. Notable bridges along the route include the Charles River bridge in Cambridge and the Connecticut River crossing between Gill and Greenfield. The highway's designation was formalized with the 1922 New England road marking system.

Major intersections

From west to east, key junctions include the western terminus at New York State Route 2 in Williamstown. It intersects U.S. Route 7 in Williamstown and again in Greenfield, and meets Interstate 91 in Greenfield. The route crosses U.S. Route 202 and Massachusetts Route 10 in Northfield. Farther east, it has interchanges with Interstate 190 in Leominster and U.S. Route 3 in Cambridge. Other significant crossings include Massachusetts Route 12 in Fitchburg, Massachusetts Route 31 in Gardner, and Massachusetts Route 128 (I-95) in Lexington.

Auxiliary routes

The primary auxiliary route is Massachusetts Route 2A, which follows several historic alignments bypassed by the main Route 2 freeway, particularly through Fitchburg, Acton, and Concord. Other related state highways include Massachusetts Route 111, which shares a brief concurrency in Littleton, and Massachusetts Route 140, which begins at an interchange in Gardner. The western scenic section also connects to several spur routes leading to recreational areas like the Mohawk Trail State Forest and Savoy Mountain State Forest.
