U.S. Route 3

U.S. Route 3 is a north–south United States Numbered Highway running approximately 274 miles from Cambridge, Massachusetts to the Canada–United States border at Third Connecticut Lake in Pittsburg, New Hampshire. It serves as a vital corridor through the heart of New England, connecting the dense urban area of Greater Boston with the scenic Lakes Region and White Mountains of New Hampshire. The highway is notably the primary route for travel from Boston to the popular tourist destinations of Franconia Notch State Park and the New Hampshire North Country.

Route description

From its southern terminus at a junction with Massachusetts Route 2 in Cambridge, Massachusetts, the route traverses the densely populated suburbs northwest of Boston, including Arlington and Burlington. It briefly coincides with the path of the historic Battle Road near the Minute Man National Historical Park. Crossing into New Hampshire at Nashua, it becomes a major commercial artery, passing through Manchester and Concord, the state capital. North of Plymouth, the character of the highway shifts dramatically as it enters the rugged terrain of the White Mountain National Forest, winding through the dramatic landscapes of Franconia Notch and past iconic natural features like the Old Man of the Mountain historic site. Its final miles are a remote, two-lane road through the Great North Woods Region of New Hampshire, terminating at the Canadian border in Pittsburg.

History

The highway was originally designated as part of the United States Numbered Highway System in 1926, largely following pre-existing named auto trails like the Daniel Webster Highway. Its initial routing ended at the Quebec border near Beecher Falls. Significant realignments occurred with the construction of new highways, particularly in Massachusetts, where much of its original path was supplanted by the construction of the Northwest Expressway project, which later became part of the Interstate 95 corridor. In New Hampshire, the route was incrementally improved and straightened over decades, with a major bypass constructed around Laconia in the 1950s. The northernmost segment, extending to Third Connecticut Lake, was formally designated in the early 1970s, solidifying its role as a key border crossing.

Major intersections

Key junctions along the route include its southern terminus at Massachusetts Route 2 in Cambridge and interchanges with Interstate 95 and U.S. Route 20 in Burlington. In New Hampshire, it intersects with the Everett Turnpike in Nashua, Interstate 293 and U.S. Route 202 in Manchester, and Interstate 393 and U.S. Route 4 in Concord. Farther north, it meets the eastern terminus of U.S. Route 302 in Bethlehem and the western terminus of the Kancamagus Highway (New Hampshire Route 112) in Lincoln. Its final major junction is with U.S. Route 2 in Lancaster before continuing to the border.

Auxiliary routes

U.S. Route 3 has one current auxiliary route, U.S. Route 3 Business through downtown Manchester, which follows the original alignment of the main highway. Historically, it had several other business routes and spurs in cities like Nashua and Concord, but these have been decommissioned or renumbered over time, often becoming state-maintained routes such as New Hampshire Route 3A. These auxiliary routes typically served the commercial centers of the cities bypassed by later realignments of the main U.S. Route 3.

In popular culture

The highway has been referenced as a landmark and setting in various works, most notably providing the title and central motif for the 2004 film Interstate 60, though the film's fictional road is not an actual highway. The route's passage through the White Mountains has inspired numerous travelogues and photography books highlighting New England scenery. It is also frequently mentioned in regional literature and folklore related to the Old Man of the Mountain and the Appalachian Trail, which it crosses in Franconia Notch. The remote northern stretch features in accounts of North Country history and logging in the Great North Woods Region.
