New Hampshire Route 4 (NH 4) is a 3.78-mile (6.08 km)
For most of its length NH 4 is signed as an east–west highway. Signage in downtown Dover while overlapped with NH 9 and NH 108 is inconsistent as it is sometimes signed north–south. In general, NH 4 follows a southwest-to-northeast alignment.

Route description
Western terminus
The western terminus of NH 4 is not readily apparent, but signage suggests it to be at the intersection of Central Avenue and Silver Street (where NH 9 and NH 108 split). Signage at the intersection of Silver Street and Central Avenue seems to indicate NH 4 continuing westbound along NH 9; however, no further signage for NH 4 exists west of this point.
Downtown Dover
From the intersection of Central Avenue and Silver Street, NH 4 is overlapped with NH 9 and NH 108 for 0.5 miles (0.80 km), until NH 4 splits off in the center of town. The exact routing differs depending on which direction one is traveling, due to the one-way streets it traverses in the downtown area.
In the eastbound direction, NH 4 is overlapped with NH 9 east / NH 108 north onto Main Street then splits off onto Portland Avenue, on which it remains.
However, in the westbound direction NH 4 (as signed) splits from Portland Avenue onto Chapel Street. It then turns right onto Saint John Street, left onto Broadway, then left onto Central Avenue (NH 9 west / NH 108 south).
Westbound Portland Avenue from Chapel Street to Main Street is signed as a
Rollinsford
After leaving downtown Dover, NH 4 crosses into the town of Rollinsford. It is the only state route to pass through Rollinsford and runs in the south-central part of town for about 2.5 miles (4.0 km). NH 4 then crosses the Salmon Falls River into the town of South Berwick, Maine, and becomes Maine State Route 4 (which is signed as a north–south highway).
NH 4 is named Portland Avenue in Rollinsford.
History
NH 4 (and
US 4 only travels through a small section of southern Dover (mostly along the Spaulding Turnpike) which is several miles from downtown, meaning it was unlikely that the two highways would be easily confused.
Major intersections
The entire route is in Strafford County.
