U.S. Route 5
highway in the United States
U.S. Route 5 (US 5) is a north–south United States Numbered 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 (I-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 Canada–United States border, where it continues past the Derby Line–Stanstead Border Crossing into Quebec as Route 143, which was Route 5 until renumbered in the mid-1970s. Its southern terminus is in New Haven, Connecticut, at an intersection with I-91.
Route description
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 US 5's entire length, it remains its own road entirely separate from I-91, which has largely replaced it as a through route (and now carries most of the traffic).

Why this record matters
“U.S. Route 5” is worth following because a concise public description often conceals a longer documentary argument. Here, Route, highway and United provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 4, 2026. The linked authority identifier is Q406273. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
