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.
