Interstate 91 (I-91) is an Interstate Highway in the New England region of the United States. It provides the primary north–south thoroughfare in the western part of the region. The Interstate generally follows the course of the Connecticut River. Its southern end is in New Haven, Connecticut, at Interstate 95. The northern end of the American-maintained road is in the village of Derby Line, Vermont, at the Canadian border. I-91 then continues past the Derby Line–Rock Island Border Crossing, where the road's official name changes to Autoroute 55. I-91 is the longest of three Interstate highways whose entire route is located within the New England states and is also the only primary (two-digit) Interstate Highway in New England to intersect all five of the others that run through the region. The largest cities along its route are New Haven, Connecticut, Hartford, Connecticut, Springfield, Massachusetts, Northampton, Massachusetts, Greenfield, Massachusetts, Brattleboro, Vermont, White River Junction, Vermont, and St. Johnsbury, Vermont in order from south to north.
Interstate 89 (I-89) is an Interstate Highway in the New England region of the United States traveling from Bow, New Hampshire, to the Canadian border between Highgate Springs, Vermont, and Saint-Armand, Quebec. As with all odd-numbered primary interstates, I-89 is signed as a north–south highway. However, it follows a primarily northwest-to-southeast path. The route forms a substantial part of the main connection between the cities of Montreal and Boston. In Quebec the route continues as Quebec Route 133. The eventual completion of Autoroute 35 from Montreal will lead to a non-stop limited access highway route between the two cities, following I-93 south from I-89's terminus. The largest cities directly served by I-89 are Concord, the state capital of New Hampshire, Montpelier, the state capital of Vermont, and Burlington, Vermont. I-89 is one of three main Interstate highways whose route is located entirely within New England, along with I-91 and I-93.
Interstate 86 may refer to any of three unconnected Interstate Highways in the United States:
U.S. Route 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.
Interstate 84 (I-84) is an Interstate Highway in the northeastern United States that extends from Dunmore, Pennsylvania, at an interchange with I-81 east to Sturbridge, Massachusetts, at an interchange with the Massachusetts Turnpike (I-90). Among the major cities that the road passes through is Hartford, Connecticut. Another highway named I-84 is located in the northwestern United States.
Interstate 395 (I-395) is an auxiliary Interstate Highway in the U.S. states of Connecticut and Massachusetts; it is maintained by the Connecticut Department of Transportation (ConnDOT) and the Massachusetts Department of Transportation (MassDOT). Spanning nearly 67 miles (108 km) on a south–north axis, it is the only spur route of Interstate 95 in Connecticut. The 36-mile (58 km) section between its splits from I-95 in East Lyme and Route 695 in Plainfield is a component highway of the Connecticut Turnpike. Within that state, the highway is named the American Ex-Prisoner of War Memorial Highway from Plainfield to Thompson.
Interstate 291, also known as the Springfield Expressway, is a 5.44-mile (8.75 km) connector highway in Massachusetts that links Interstate 91 in downtown Springfield with Interstate 90 in Chicopee. I-291 is roughly a northeast/southwest highway. It merges with I-91 at its southwestern terminus, via a flyover. The road meets the Mass Pike at its northeastern terminus. Getting onto the Pike from I-291 is straightforward, but getting from the Pike to I-291 requires a left turn at an at-grade traffic signal. I-291 travels directly through highly populated areas of Springfield, and passes under several overpasses. From its southwestern terminus to exit 5A, Interstate 291 is concurrent with U.S. Route 20.
Interstate 291 is the designation for two Interstate Highways in the United States, both of which are related to Interstate 91:
New Hampshire Route 12 is a 62.773-mile (101.023 km) long north-south state highway in southwestern New Hampshire. Its southern terminus is at the Massachusetts state line in Fitzwilliam, where it continues south as Massachusetts Route 12. Its northern terminus is at the Vermont state line in Claremont, where it continues north as Vermont Route 12. Most of the northern part of NH 12 runs along the Connecticut River.
Route 9 is a 40.89-mile (65.81 km), 4-lane freeway beginning in Old Saybrook and ending at I-84 near the Farmington-West Hartford town line. It connects the Eastern Coastline of the state along with the Lower Connecticut River Valley to Hartford and the Capital Region.
U.S. Route 20 runs its easternmost 153 miles (246 km) in the U.S. state of Massachusetts. The highway crosses the state border from New Lebanon, New York, into Hancock, Massachusetts, and runs eastward into Boston, where it ends at Route 2 in Kenmore Square. It spends the vast majority of its journey paralleling the Massachusetts Turnpike, which has largely superseded US-20 for through travel. Still, US-20 directly serves many towns and local business areas which the Turnpike bypasses.
Interstate 84 (I-84) is an east–west Interstate highway across the state of Connecticut through Danbury, Waterbury, Hartford and Union.
Transportation in New England encompasses the region's rail and highway networks, seaports, and airports. New England has one of the United States' oldest intercity transportation systems, which remain important to the region's economy. It is also home to the continent's first subway system. The densely populated area has many cities and towns connected by rail and road, and the larger cities each have commercial airports with daily flights to destinations outside of the region.
