U.S. Route 7

US 7 in Connecticut (also known as Route 7, Ethan Allen Highway and Super 7) is mostly a surface road but has two short expressway sections in the Norwalk and Danbury areas. US 7 begins in Norwalk with a 4-mile (6.4 km) expressway to nearly the Wilton town line. There are three exits on this short section, signed as "The Forty Third Infantry Division Memorial Highway". Exit 1, just past I-95 (the southern terminus), leads to the Central Norwalk Business District and US 1. Exit 2 leads to Route 123 which extends from US 1 in Norwalk to the New York State line, passing through the town of New Canaan. After exit 2, the expressway reduces to four lanes from six. Exit 3 leads to Route 15 southbound, also known as the Merritt Parkway. This interchange was half built and only allows southbound access from the expressway; northbound access is gained via Route 123 at exit 2. The expressway section ends at Grist Mill Road in Norwalk, about one-half mile past exit 3. Route 7 then passes through Wilton as a 4-lane highway until just after Cannondale, where it becomes a 2-lane highway. It continues through Ridgefield as a 2 lane highway.

Near Danbury, another expressway section was built beginning 1-mile (1.6 km) south of I-84 near the Danbury Airport. This section is also signed as "The Forty Third Infantry Division Memorial Highway". Through Danbury proper, Route 7 overlaps with I-84 for about 4 miles (6 km). Through this section of expressway, Routes I-84, US 7, US 6 and US 202 are concurrent. Routes 7 and 202 then leave I-84 at exit 7 and travel on their own expressway for approximately 8 miles (13 km) to just south of the New Milford line. On this section there are two exits. At exit 11 (Federal Road), US 202 exits the expressway and at exit 12, Route 202 crosses back over Route 7. On southbound Route 7, the exit for I-84 eastbound is signed as exit 10. There is no exit number for I-84 west because of the concurrency. The Route 7 expressway then bypasses Brookfield to the west and terminates at an intersection with Route 202 at the Fairfield/Litchfield county line. Construction on the section between I-84 and exit 12 began in 1974 and completed in 1976. The Brookfield bypass segment between exit 12 and the current expressway terminus opened in November 2009, after two years of construction. The former US 7 route through Brookfield is now signed solely as US 202.

Route 7 is cosigned with US 202 until central New Milford, where Route 202 turns east with Route 67 while Route 7 continues north. Recent construction has also made large parts of Route 7 between the terminus of the expressway and New Milford a four-lane divided highway with at-grade intersections. North of New Milford center, Route 7 remains a two-lane road through the rest of Connecticut and leaves Connecticut in the town of North Canaan.

US 7 enters Massachusetts in the town of Sheffield and remains a two-lane road until Lenox. There, a four-lane bypass of Lenox was built in two pieces, and the old US 7 is now Route 7A. US 7 continues on as a four-lane road to Pittsfield, where it is then a three-lane road, narrowing to two lanes for a short time, then widening to four lanes in downtown Pittsfield. US 7 leaves downtown Pittsfield as a two-lane surface arterial, and continues as a rural highway with occasional three-lane stretches for climbing the grades along the Berkshires. It passes west of Mount Greylock before passing through Williamstown, connecting the Taconic Trail with the Mohawk Trail. The road passes Williams College before entering Vermont.'

Like Connecticut, Massachusetts planned a US 7 expressway from the existing bypass in Lenox all the way to Lanesborough. This plan was never initiated, although land takings occurred. The highway was ultimately canceled due to environmental and community opposition.

In Massachusetts, Route 7 passes through the towns of Sheffield, Great Barrington, Stockbridge, Lee, Lenox, Pittsfield, Lanesborough, New Ashford, and Williamstown, before crossing into Pownal, Vermont.

US 7 remains a rural two-lane highway from the Massachusetts line to Bennington, Vermont, where a freeway is being built to the north and east of Bennington. Once complete, US 7 will utilize this new bypass while the existing two-lane road into town will become part of Vermont Route 7A (VT 7A). North of town, the highway then again returns to expressway status. For 3 miles (5 km), it is a true expressway with divided carriageways and multiple lanes. Route 7 then narrows down to an undivided two-lane freeway. There are, however, many stretches with passing lanes. Just north of Manchester the expressway ends. From Manchester to Wallingford, the road is two lanes and rural. North of Wallingford, US 7 becomes a four lane divided highway with at-grade intersections, until its southern junction with US 4, south of the city of Rutland. From Rutland north, the road is either two-lane or four-lane undivided, uncontrolled road all the way to the Canada–US border except between Shelburne and Burlington, which is a four-lane divided highway. US 7 and US 2 are concurrent from Burlington to Colchester. It is known as the Ethan Allen Highway for much of the path through Vermont.

In Vermont it passes through the towns of Pownal, Bennington, Shaftsbury, Glastenbury, Arlington, Sunderland, Manchester, Dorset, Danby, Mt. Tabor, Wallingford, Clarendon, Rutland, the city of Rutland, the towns of Pittsford, Brandon, Leicester, Salisbury, Middlebury, New Haven, Waltham, Ferrisburg, Charlotte, Shelburne, the cities of South Burlington at which point I-89 begins to parallel it, Burlington, and Winooski, the towns of Colchester, Milton, Georgia, St. Albans, the city of St. Albans, and the towns of Swanton and Highgate before ending at I-89 just south of the customs offices at the Canada–US border.
