U.S. Route 7 in Vermont

U.S. Route 7 (US 7) is a north–south highway extending from southern Connecticut to the northernmost part of Vermont. In Vermont, the route extends for 176 mi along the western side of the state as a mostly two-lane rural road, with the exception of an expressway section between Bennington and East Dorset. US 7 is known as the Ethan Allen Highway for its entire length through the state, named after the US Revolutionary War general. US 7 ends at an interchange with Interstate 89 (I-89) in the town of Highgate, just south of the Canada–United States border. I-89 continues to the border crossing.

Route description
US 7 crosses the Massachusetts–Vermont state line at Pownal, from where the road heads north to Bennington as a rural two-lane highway. Just north of downtown Bennington, the highway transitions into a limited-access highway. For 3 mi, US 7 is a true expressway with divided carriageways and multiple lanes. The road subsequently narrows down to an undivided two-lane freeway; however, many stretches have passing lanes. This continues to a point just south of East Dorset, where US 7 reverts to a surface road.

Most of US 7 between East Dorset and the Canada–United States border is an undivided, uncontrolled road varying in width from two to four lanes. Two divided highway sections also exist: a 10 mi section south of Rutland and a 3 mi stretch with numerous traffic signals between Shelburne and South Burlington known as Shelburne Road. There is overhead signage at the junction with I-189 in South Burlington that directs northbound trucks onto I-189. While US 7 heads directly into Burlington, I-189 bypasses the city to the south and east and leads directly to I-89, which runs close to US 7 north of Winooski.

Near downtown Burlington, US 7 intersects with US 2; the latter route joins US 7 for more than 9 mi to Colchester. From here, US 7 and I-89 run through northern Vermont to Highgate, where US 7 ends at the northernmost exit on I-89.

History
US 7 was assigned in 1926. I-89 was originally envisioned to parallel US 7 from the Canadian frontier to the Massachusetts border. This plan was ultimately canceled, and I-89 was shifted to its current alignment, turning southeast at Burlington toward Montpelier and White River Junction. Prior to the cancelation of the original I-89 routing, approximately 25 mi of freeway (mostly super two with some four-lane sections) was built in the US 7 corridor between Bennington and Manchester, plus an additional 7 mi of four-lane highway between Wallingford and Rutland were completed.

Suffixed routes
US 7 has two suffixed routes, both of which are old alignments of US 7.
 * VT 7A (27.820 mi) is an alternate route of US 7 between Bennington and Dorset. The route is signed as "Historic VT 7A" to distinguish it, the original routing of US 7, from the modern US 7 limited-access highway.
 * VT 7B (6.786 mi) is an alternate route of US 7 through the towns of Wallingford and Clarendon. VT 7B was the original alignment of US 7 prior to the construction of the current US 7 divided highway through the area. The route intersects US 7 five times (including the terminuses) and overlaps it for 0.716 mi in Clarendon.

US 7 Alternate
U.S. Route 7 Alternate (US 7 Alt.) is an alternate route of US 7 in Burlington. The southbound-only US 7 Alt. begins at the intersection of Hyde Street and Riverside Avenue (US 2 and US 7) and runs for a distance of 2.107 mi in the following manner: west on Riverside Avenue, south on North and South Winooski avenues, south on St. Paul Street, and south on Shelburne Street to its end at US 7 at a roundabout intersection with South Willard Street (US 7) and Locust Street. Mainline US 7 travels over Hyde Street and North and South Willard streets until the aforementioned intersection.

As of July 2016, there are three US 7 Alt. assemblies along the route. The original one is located on Saint Paul Street in Burlington, just south of the intersection with South Winooski Avenue and Howard Street, with the newer two on South Winooski Avenue, with one at the intersection with Pearl Street, and the other at Main Street.

, in conjunction with the reconstruction of the rotary-style intersection where US 7 Alt. terminates, there is a new directional US 7 Alt. sign installed in the rotary, along with a lone reassurance US 7 Alt. marker installed just to the north.
