New Hampshire Route 4A
Location:	Lebanon-Andover
Length:	23.955 mi (38.552 km)

In the state of New Hampshire, U.S. Route 4 runs for 106.8 miles (171.9 km) across the central and southern part of the state, stretching from Lebanon on the Connecticut River border with Vermont southeast to Portsmouth on the eastern coast.

U.S. Route 4 crosses the Connecticut River into New Hampshire in the community of West Lebanon, where it immediately intersects Route 10 which runs parallel to the river. US-4 turns south onto Route 10, and the two routes turn south, meeting Route 12A before turning towards and interchanging with Interstate 89. At this point, Route 10 joins the I-89 freeway southbound, while US-4 continues east into downtown Lebanon. The road crosses Route 120, continues east and interchanges with I-89/Route 10 again. US-4 continues east away from the freeway into Mascoma, where Route 4A splits off to the southeast. US-4 continues east through Enfield and into Canaan, where it meets the southern end of Route 118. The road turns to the south at this point, passing through Grafton and Danbury, where US-4 meets the west end of Route 104 and continues south into Andover. In Andover, US-4 turns back to the east and meets Route 11 near Route 4A's eastern terminus. US-4 and Route 11 run concurrently through Andover for about 2 miles (3.2 km) before splitting, Route 11 to the northeast and US-4 to the southeast. US-4 enters the town of Salisbury and crosses Route 127, before continuing into Boscawen and intersecting with U.S. Route 3. US-3 and US-4 share a short concurrency (about a mile), before US-4 turns east to interchange with Interstate 93 at Exit 17.
