Along with Route 9 and U.S. Route 20 to the south, these highways are the main alternatives to the Massachusetts Turnpike/I-90 toll highway. Route 2 runs the entire length of the northern tier of Massachusetts, beginning at the New York border, where it connects with New York State Route 2, and ending near Boston Common in Boston. ==Route description== 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 of 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, Massachusetts. 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 and Leominster, where Interstate 190 heads south to Worcester. Continuing east into Fitchburg, Route 2 has several at-grade intersections with Oak Hill Road, Palmer Road, Mt. Elam Road, and Abbott Avenue. At the intersection with Mt. Elam Road, a traffic light remains in use on the eastbound side. Route 2 continues east to Middlesex County, Massachusetts 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 Road and Taylor Road, 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 used to then break 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 goes straight while Route 2 veers right (but still heads east). The highway loses its dividing wall until the Bedford St. intersection in Lincoln where it becomes divided again. MassHighway currently expects to rebuild the Crosby Corner intersection and create a dividing wall from there to Bedford St.〔Massachusetts Department of Transportation, (Project Information )〕 At this point Route 2 enters Lexington and still is a divided 4-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 Street), 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 limited access highway portion ends at a signalized 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 Avenue, Fresh Pond Parkway, Gerry's Landing Road, and Memorial Drive (all parkways maintained by the Department of Conservation and Recreation) through Cambridge. It crosses into Boston on the Boston University Bridge. The Brookline/Norfolk County line also lies upon intersecting Commonwealth Avenue. After crossing Commonwealth Avenue (U.S. Route 20), it follows Mountfort Street and Beacon Street through the northernmost tip of Brookline before crossing into Kenmore Square which is the eastern terminus of U.S. Route 20. From Kenmore Square, Route 2 follows Commonwealth Avenue to Arlington Street. It circles the Public Garden in Boston, using Arlington Street to Boylston Street to Charles Street. Route 2 goes along northbound Route 28 at the intersection of Charles Street and Beacon Street between Boston Common and the Boston Public Garden. Shortly after, Route 2 ends on U.S. Route 3 or Route 3 while Route 28 north goes with the southbound of Route 3. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Massachusetts Route 2」の詳細全文を読む スポンサード リンク
