Its southern terminus is in New Haven, Connecticut, at I-95, while the northern terminus is in Derby Line, Vermont, at the Canada–United States border. Past the Derby Line–Rock Island Border Crossing, the road continues into Canada as Quebec 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 other highways that run through the region. The largest cities along its route, from south to north, are New Haven, Connecticut; Hartford, Connecticut; Springfield, Massachusetts; Northampton, Massachusetts; Greenfield, Massachusetts; Brattleboro, Vermont; White River Junction, Vermont; St. Johnsbury, Vermont; and Newport, Vermont.
Interstate 93 (I-93) is an Interstate Highway in the New England states of Massachusetts, New Hampshire, and Vermont in the United States.

The largest cities along the route are Boston, and Manchester, New Hampshire; it also travels through the New Hampshire state capital of Concord.
U.S. Route 20 or U.S. Highway 20 (US 20) is an east–west United States Numbered Highway that stretches from the Pacific Northwest east to New England.

Spanning 3,365 miles (5,415 km), it is the longest road in the United States, and, in the east, the route is roughly parallel to Interstate 90 (I-90), which is the longest Interstate Highway in the U.S. There is a discontinuity in the official designation of US 20 through Yellowstone National Park, with unnumbered roads used to traverse the park.

The Massachusetts State Highway System in the U.S. Commonwealth of Massachusetts is a system of state-numbered routes assigned and marked by the highway division of the Massachusetts Department of Transportation (MassDOT). U.S. Highways and Interstate Highways are included in the system; the only overlaps are with the end-to-end U.S. Route 3 and Route 3 and the far-apart Interstate 295, shared with Rhode Island, and Route 295, shared with New York State. A state highway in Massachusetts is a road maintained by the state, which may or may not have a number. Not all numbered routes are maintained or owned by the state.

The Veterans of Foreign Wars Parkway is a historic parkway in Boston, Massachusetts. The southern terminus of the parkway is at Washington Street at the Dedham-West Roxbury border, from where it travels north and then east, ending at a junction with Centre Street, near the Arnold Arboretum. The highway is almost entirely contained within the West Roxbury neighborhood, although it passes through part of the Chestnut Hill neighborhood near its junction with the West Roxbury Parkway. Most of its length, from Spring Street in West Roxbury to its eastern end, is administered by the Massachusetts Department of Conservation and Recreation (DCR), a successor to the Metropolitan District Commission (MDC) which oversaw the road's construction. The parkway was built in stages between 1930 and 1942, and was designed to provide a parkway connection from the Upper Charles River Reservation to other MDC parks via the West Roxbury Parkway. The DCR portion of the road was listed on the National Register of Historic Places in 2005. The road formerly carried the designation for U.S. Route 1.
