Massachusetts Route 2

Route 2 proceeds east from the New York state line on a winding, scenic path in Berkshire County through Williamstown, where it serves the Williams College area and through North Adams, where it serves the Massachusetts College of Liberal Arts. East of North Adams, Route 2 ascends via a hairpin turn into the Hoosac Range along what is known as the Mohawk Trail.

Route 2 then enters Franklin County, meeting Interstate 91 at an interchange in Greenfield and briefly runs concurrently with I-91. While the old Route 2 becomes Route 2A and goes through downtown Greenfield, Route 2 exits off I-91 as a short expressway before becoming a two-lane freeway. Outside Greenfield, Route 2A temporarily ends and merges with Route 2. Route 2 remains a regular two-lane surface road in Gill and through Erving, though it has some grade-separated interchanges in Millers Falls at its intersection with Route 63. There is another gap in the two-lane expressway in the Erving area. Recently, the road in Erving was routed to the north and straightened to avoid the paper mill next to the river. This rerouting led to the road being shortened by less than a tenth of a mile.

Once the road enters the Town of Orange, Route 2A resumes and diverges from Route 2. At this point, Route 2 again becomes a two-lane expressway. In Orange, Route 2 runs concurrently with U.S. Route 202. The road at this point enters the town of Athol in Worcester County. After its eastern interchange in Phillipston when US-202 departs to the north, Route 2 becomes a full four-lane expressway, though not to Interstate standards at most points. It continues through Gardner into Fitchburg where Route 2 has several at-grade intersections with Oak Hill Rd, Palmer Rd, Mt. Elam Rd and Abbott Ave. At the intersection with Mt. Elam Rd, a traffic light remains in use on the eastbound side. Continuing east into Leominster, Interstate 190 splits off, heading south to Worcester.

Route 2 continues east to Middlesex County and enters Boston's outer loop at the interchange with Interstate 495 in Littleton. It continues as an expressway into Acton, where the expressway ends at the traffic light intersection with Piper Rd and Taylor Rd, and Route 2 becomes a regular divided highway at most points and just a four-lane highway at other points. At the Concord Rotary, a major traffic choke point, Route 2 intersects with Route 2A and the eastern terminus of Route 119 (which is concurrent with Route 2A). After the rotary, the road loses its dividing wall as it passes by the State Police (who have an emergency-only traffic light) and over the Assabet River. Route 2A formerly broke away from Route 2 at the next traffic light to go left into Concord but is now overlaid with Route 2. At Crosby's Corner, the sixth intersection after the rotary, Route 2A exits under the highway while Route 2 veers right (but still heads east). While the highway is divided across Lincoln, there is a single traffic light intersection at Bedford Rd.

Convergence of Routes 2, 3, and 16 at Alewife.

At this point, Route 2 enters Lexington and still is a divided four-lane road with surface intersections. It then heads to Boston's inner belt, crossing Interstate 95/Route 128. In Arlington, Route 2 is a six-lane and then eight-lane limited-access highway until east of Exit 60 (Lake St), where it narrows with little warning to six lanes and then to four lanes. This section of expressway actually meets the standards of an interstate highway. The final off-ramp leads toward the large parking garage at the MBTA Alewife Station. At this point the road heads into Cambridge.

The shield for Massachusetts Route 2, located across from the Boston Common

The limited access highway portion ends at a signalled intersection, where it merges with U.S. Route 3 south and Route 16 west in Cambridge and continues as a four-lane surface road to the Boston Public Garden. Route 2 follows Alewife Brook Parkway, Concord Ave, Fresh Pond Parkway, Gerry's Landing Rd, and Memorial Drive (all parkways maintained by the Department of Conservation and Recreation) through Cambridge. It crosses into Boston heading southward on the Boston University Bridge. It winds through the Boston University campus as Mountfort Street and crosses over both the Massachusetts Turnpike and Commonwealth Avenue before heading due east towards Kenmore Square, while running parallel to U.S. Route 20. Immediately east of the Boston University campus, it crosses into Kenmore Square, which is also the eastern terminus of U.S. Route 20. From Kenmore Sq, Route 2 follows Commonwealth Ave to Arlington St. It circles the Public Garden, using Arlington St to Boylston St to Charles S. Route 2 goes along northbound Route 28 at the intersection of Charles St and Beacon St between Boston Common and the Public Garden. Shortly after, Route 2 ends on U.S. 3 or Route 3 while Route 28 north joins with the southbound of Route 3.

The route amalgamates and supersedes various named highways in some cases going back to the pre-automobile era. For example, parts of Route 2 are sometimes known as the Cambridge and Concord Turnpike and the Mohawk Trail.

In the early 1920s, Route 2 was known as New England Interstate Route 7 (NE-7), a major road connecting Boston with Troy, New York. NE-7 ran roughly where Route 2A (the original surface alignment of Route 2) does now except near the New York state line. NE-7 used current Massachusetts Route 43, New York State Route 43 and New York State Route 66 to reach Troy. Current Route 2 from Williamstown to Petersburgh was previously numbered as Route 96.

Route 2 connected as a highway in its current right-of-way at Alewife Brook Parkway at some point before 1937.[2]

An upgraded Route 2 was originally planned to continue as Boston's Northwest Expressway (merging with a re-routed U.S. Route 3 at the Arlington-Lexington or Arlington-Cambridge border) to a junction with Interstate 695, the Inner Beltway, but this, along with the Inner Beltway itself, was cancelled in 1970, accounting for the abrupt narrowing at Alewife.[3][4] In place of the highway project, the MBTA Red Line was extended from Harvard to Alewife in the 1980s.

The Leominster to Ayer section opened on July 3, 1953, completing the expressway portion from Westminster to West Concord.[5] Full grade separation between Route 128 and Alewife Brook Parkway was completed around 1970.

MassDOT is scheduled to replace the old sequential exit numbers with the new milepost-based exit numbers beginning in summer 2020,[9][10] which have been delayed since 2016.[11][12]
