New Hampshire Route 108 is a 42.430-mile-long (68.284 km) north–south state highway in Rockingham and Strafford counties in southeastern New Hampshire. The southern terminus of NH 108 is at the Massachusetts state line in Plaistow. The northern terminus is at an intersection with New Hampshire Route 125 and New Hampshire Route 202A in downtown Rochester.
NH 108 is notable in being one of two routes (the other being New Hampshire Route 9) to intersect both U.S. Route 4 and New Hampshire Route 4 (a rare case of two completely separate routes in one state having the same number).
Massachusetts Route 108
Route 108 begins at an intersection with Route 110 north of downtown Haverhill, Massachusetts, near Kenoza Lake. The highway proceeds due north, passing underneath I-495 before crossing into Plaistow, New Hampshire, where it becomes NH 108.
Plaistow to Exeter
NH 108 runs along the eastern edge of Plaistow, near the Massachusetts border, before crossing through Newton into East Kingston, where it crosses NH 107A, then turns eastward to form a brief wrong-way concurrency with NH 107. Continuing north, NH 108 passes through Kensington, where it meets the north end of NH 150 and continues north into Exeter. In Exeter, NH 108 meets NH 27, NH 111 and NH 111A, forming a very brief overlap with the former two routes. NH 108 meets the western end of NH 88, then interchanges with the NH 101 freeway at exit 11.
Stratham to Dover
NH 108 crosses into Stratham where it meets NH 33, a connector to US 1 in Portsmouth which also interchanges with I-95, at a traffic circle. Continuing northward, NH 108 passes through Newfields and Newmarket, intersecting with NH 85 and NH 152 along the way. The road crosses into Durham and Strafford County, passing through the center of town just east of the University of New Hampshire main campus, and then interchanging with US 4. NH 108 continues through eastern Madbury and into the city of Dover.
Dover to Rochester
NH 108 interchanges with the Spaulding Turnpike (NH 16) at exit 7, becoming Central Avenue, the main road in downtown Dover. The road intersects NH 9 and NH 4 at Silver Street. NH 4 has its western terminus here. The three routes briefly run concurrently in the center of Dover, before NH 4 splits off towards South Berwick, Maine via Portland Avenue. NH 9 and NH 108 continue north until NH 9 splits off towards Berwick, Maine, near an intersection with the Spaulding Turnpike at Exit 9 (via Indian Brook Drive). NH 108 continues north into the city limits of Somersworth, where it meets NH 236, a short connector to NH 9 bound for Berwick. NH 108 serves as Somersworth's industrial strip, then continues north into Rochester. NH 108 terminates at the intersection of South Main Street and Columbus Avenue (NH 125), a terminus it shares with NH 202A. South Main Street continues into downtown as NH 202A westbound.
