U.S. Route 302 (US 302) is an east–west spur of U.S. Route 2 in northern New England in the United States. It currently runs 171 miles (275 km) from Montpelier, Vermont, at US 2, to Portland, Maine, at U.S. Route 1. It passes through the states of Vermont, New Hampshire and Maine.

US 302 enters Vermont after crossing the Connecticut River at the village of Wells River. The highway crosses US 5 in the center of the village. The next major intersection for US 302 is its intersection with Interstate 91 in Newbury, about 2.7 miles (4.3 km) from the US 5 intersection. US 302 then winds through the rural towns of Ryegate, Groton, Topsham, and Orange, before entering East Barre. In East Barre, its intersection with Vermont Route 110 takes the form of a roundabout. After traveling down out of the hills surrounding the city of Barre, US 302 makes up Washington Street and Main Street of Barre. It runs along the Jail Branch River and the Stevens Branch of the Winooski River in Barre, then through Berlin, finally terminating at its US 2 intersection in southeast Montpelier.

US 302 is named William Scott Memorial Highway and was part of the Theodore Roosevelt International Highway in Vermont.[3][4]

New Hampshire[edit]

US 302 enters the state of New Hampshire at a two-lane arch bridge over the Connecticut River beginning in Wells River, Vermont. It follows Central Street on a two-lane alignment, passing through Woodsville until it reaches NH 10 (Dartmouth College Highway), where it turns eastward.

US 302 follows the Ammonoosuc River through a mix of fields and forested land, passing through Bath as Lisbon Road and Lisbon as its Main Street. As it approaches Littleton, the road's name changes to Meadow Street and becomes a shopping strip just before crossing the river and interchanging with I-93. After a short stretch, the road meets Main Street (NH18) at a skewed intersection, defaulting onto Main Street and passing through the town's downtown.

The route intersects NH 116 and turns southward onto Cottage Street, immediately bridging the Ammonoosuc River once again, and passes through a residential area before turning eastward onto Bethlehem Road. The route passes under Interstate 93 again and passes through woodland, where it crosses I-93 for a third time at a second interchange, where NH 18 and NH 116 also depart to the south. US 302 then travels eastward through largely forested land, passing through Bethlehem and Twin Mountain (where it crosses U.S. Route 3), then turns southward as it passes through Crawford Notch State Park, bearing Crawford Notch Road as its name and paralleling the Saco River.

After turning eastward again, passing through Bartlett and intersecting NH 16, the road becomes White Mountain Highway and turns southward once more, passing Lower Bartlett and entering North Conway. The route follows Eastman Road south of North Conway, which it follows to its end at NH 113 (Main Street) after bridging the Saco River once again. US 302 turns east, passing through more forested land as it crosses the Maine state border, bound for Fryeburg a short stretch east of there.

US 302 is known as the Roosevelt Trail through southern Maine because it was the beginning of the Theodore Roosevelt International Highway to Portland, Oregon.[4][5] The highway leaves Portland, Maine, bridging the Presumpscot River into Westbrook at Riverton. The Roosevelt Trail then bridges the Pleasant River at milepost 13.4 in Windham, the Crooked River in Casco near a boyhood home of Nathaniel Hawthorne, Long Lake near milepost 31 in Naples, Moose Pond near milepost 46 in Bridgton, and the Saco River near milepost 56 in Fryeburg. The highway follows the Saco River from Fryeburg into the White Mountains and enters New Hampshire near milepost 58.[6] It is a two-lane highway for almost all of its length, but there are multi-lane sections within the Portland area, as well as short four-lane sections in and around North Windham (especially the commercial areas). Some of the hilly sections also feature a third passing lane.


The eastern end of US 302 was formerly at Longfellow Square in Portland, Maine. The highway follows a 19th-century stagecoach road from Portland through Windham to Bridgton. The portion from Windham to Bridgton was built about 1785. Stagecoach service began in 1803, and the route became a post road for the United States Postal Service in 1814. Transportation over this route was augmented by the Cumberland and Oxford Canal from 1832 to 1932, and by the Bridgton and Saco River Railroad from 1883 to 1941.[7] The highway through Crawford Notch follows the Tenth New Hampshire Turnpike built in 1803 and parallels the Maine Central Railroad Mountain Division built in 1877. The highway eliminated railway passenger travel over the route from Portland by 1958, and railroad freight service through Crawford Notch was discontinued in 1983.[8]

Length 54.18 mi (87.19 km)
Existed 1926–1935

From 1922 until 1935, much of what is now US 302 was a part of the New England road marking system, designated as Route 18, from Portland, Maine, northwest to Littleton, New Hampshire, roughly 112 miles (180 km). From Littleton west to Montpelier in Vermont, US 302 and Route 18 took different paths. NE-18 took a more northerly route, along present-day New Hampshire Route 18 and Vermont Route 18 to St. Johnsbury, Vermont (closely paralleling I-93), then along present-day US 2 up to Montpelier.

Current US 302 runs along a more southerly route using other former sections of New England Interstate Routes. From Littleton, it went along former Route 10 to Woodsville, New Hampshire, then along former Route 25 to Montpelier.

The entire Maine segment of US 302 was formerly designated State Route 18, a route that was established in 1926 until being deleted in 1935 by US 302.
