Running from Tyngsborough, Massachusetts, up to the junction of Main Street, South Main Street, and East Dunstable Road, D.W. Highway in Nashua is the main thoroughfare for the South Nashua Commercial District in the southeastern portion of the city. Before the construction of the Everett Turnpike, this was also designated as U.S. Route 3. Access between the D.W. Highway and Route 3/Everett Turnpike:

• Full access via East Dunstable Road at Turnpike Exit 4.
• Partial access at Turnpike Exit 3; there is no Turnpike exit on the northbound side.
• Full access between the two roads at Turnpike Exit 2 (Circumferential Highway).
• Full access via Spit Brook Road at Turnpike Exit 1.
• Partial access at Route 3 Massachusetts Exit 91 (Middlesex Road); there is no southbound Route 3 exit here.

The main road in Merrimack, the highway runs from the southeastern to northeastern portion of town, just east of the Everett Turnpike. It continues into Bedford, crossing to the west of the Everett Turnpike, and passing through the town's main commercial district, ending at the town's northern border with Manchester, where it becomes Second Street.Access between the D.W. Highway and the Turnpike:

• At Turnpike Exit 7 via the Henri Burque Highway to Concord Street.
• At Turnpike Exit 10 (Industrial Drive)
• At Turnpike Exit 11 (Continental Boulevard)
• At Turnpike Exit 12 (Bedford Road)
• At New Hampshire Route 101 in Bedford, just west of Interstate 293 Exit 3 (where it merges with the Everett Turnpike)

Beginning at Webster Street near Livingston Park in north Manchester, heading past Interstate 93, this D.W. Highway is the main commercial thoroughfare in Hooksett, continuing northbound east of the Merrimack River to the town boundary with Allenstown, where US 3 becomes Allenstown Road.

In Pittsburg, the highway passes, in order proceeding northbound, to the north of Lake Francis, to the east of Back Lake, to the west of both the First Connecticut Lake and Second Connecticut Lake, and to the east of the Third Connecticut Lake. The highway reaches its northern terminus at the border with Canada, where the Pittsburg–Chartierville Border Crossing is located. Travel northward from that point is via Quebec Route 257.

The section of the highway from the Second Connecticut Lake to the Canadian border was constructed to provide access to the border station, which first opened on July 30, 1939.^[4] The 10 miles (16 km) of roadway, originally unpaved, was built by the Civilian Conservation Corps (CCC).^[5] This northernmost section of the highway was formally dedicated on September 24, 1939.^[6] A sign noting that date, along with the name of the road's key proponent, local politician George D. Roberts, can be seen along the road approximately 200 yards (180 m) south of the border.
