|direction_b=North |terminus_b= in Stanstead, QC }} U.S. Route 5 (US 5) is a north–south United States highway running through the New England states of Connecticut, Massachusetts, and Vermont. Significant cities along the route include New Haven, Connecticut; Hartford, Connecticut; and Springfield, Massachusetts. From Hartford northward to St. Johnsbury, Vermont, the road closely follows the route of the Connecticut River. The entire route of US 5 is closely paralleled by Interstate 91. US 5 now serves as the local business route and alternate route for the Interstate highway. The northern terminus of US 5 is in Derby Line, Vermont at the Canadian border, where it continues past the Derby Line-Stanstead Border Crossing into Quebec as Quebec Route 143, which was Route 5 until renumbered in the mid-1970s. Its southern terminus is in New Haven, Connecticut at an intersection with Interstate 91.〔(【引用サイトリンク】title=Endpoints of US highways )〕 ==Route description== |- |CT || 54.59 || 87.85 |- |MA || 53.43 || 85.99 |- |VT || 192.32 || 309.50 |- !Total !! 300.34 !! 483.35 |} US 5 runs through three states, Connecticut, Massachusetts, and Vermont, with the latter containing over half of US 5's total distance. Throughout nearly all of U.S. 5's entire length, it remains its own road entirely separate from Interstate 91, which has largely replaced it as a through route (and now carries most of the traffic). It is only co-signed onto I-91 for less than half of a mile in Springfield, MA, before splitting off alone again. US 5 begins in the city of New Haven, heading north through Hartford to Massachusetts. It generally parallels Interstate 91. From Meriden northward through Wethersfield, it runs concurrent with CT Route 15 and is known locally as the Berlin Turnpike. Much commerce is located there resulting in high traffic. The Berlin Turnpike leaves the roadway south of the Hartford city line. After an interchange in Hartford with I-91, US Route 5/CT Route 15 travels over the Charter Oak Bridge, which spans the Connecticut River, into East Hartford. US Route 5 then splits off to head towards downtown East Hartford. It then has a short overlap with US Route 44, which joins it from the west as Connecticut Boulevard. US Route 44 continues to the east along Burnside Avenue as US Route 5 continues northward into South Windsor, East Windsor and Enfield. It leaves the state soon after a junction with I-91, heading into Longmeadow, Massachusetts (a part of the Springfield metro area). US 5 stays very close to the Connecticut River. It enters the state at the town of Longmeadow on the east bank of the river going up to Springfield. In Springfield, US 5 then overlaps with Interstate 91 for about , then separates as its own freeway crossing the Connecticut River on the South End Bridge into Agawam. The freeway portion runs for about up to West Springfield. From the town of Northampton up to Bernardston, US 5 overlaps Massachusetts Route 10 (for 26 miles). US 5 also passes through Holyoke, Hatfield, Whately, Deerfield, and Greenfield. As in Connecticut, US 5 has many interchanges with the parallel I-91. US 5 follows the Connecticut River Valley from the southern border of Vermont, traveling along the west bank of that river until it reaches St. Johnsbury. US 5 enters the state at the town of Guilford. It passes through the counties of (from south to north) Windham, Windsor, Orange, Caledonia, and Orleans. Near the town of St. Johnsbury, US 5 continues northward, following the Passumpsic River valley until it reaches Sheffield Heights. After crossing the heights, it follows the Barton River valley until it reaches Orleans. It then turns north-northwest and crosses the divide near the Airport Road in Irasburg and follows the Black River valley into Newport. US 5 ends at the Canadian border in the village of Derby Line, where the roadway continues into Canada as Quebec Route 143. As in Connecticut and Massachusetts, US 5 has many interchanges with Interstate 91, with a total of 22 junctions over its length in the state. 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「U.S. Route 5」の詳細全文を読む スポンサード リンク
