all other traveled highways which a town has the duty to maintain regularly and shall be known as town roads Class VI – all other existing public ways, including all highways discontinued as open highways and made subject to gates and bars, except Class III-a roads, and all highways which have not been maintained and repaired by the town for travel thereon for 5 or more successive years Under RSA 229:5, V, the Commissioner of Transportation may establish compact sections in the following cities and towns: Routes crossing state lines Two New Hampshire state routes cross state lines while retaining their designations and NHDOT maintenance: NH 113B, a loop of Maine State Route 113 unrelated to NH 113 (despite their relatively close proximity), runs within the towns of Chatham, New Hampshire and Stow, Maine. NH 153 crosses into the town of Parsonsfield, Maine for to go around Province Lake, then runs directly on the state border between Parsonsfield and Effingham, New Hampshire for another before returning to New Hampshire. Maine State Route 113 crosses into and out of New Hampshire twice. It runs for within the town of Conway and for within the town of Chatham. SR 113 remains under MaineDOT maintenance along both of these stretches. Signage practices State highways State highways in New Hampshire are marked using square route shields depicting the Old Man of the Mountain. Unlike its neighboring states, New Hampshire does not use elongated shields for route markers, but uses condensed fonts for three-digit routes instead. Alternates of two- and three- digit routes (e.g. NH 115A) are signed with the parent highway's number over the letter of the alternate. For multiple alternates of the same route, the state generally uses sequential letters. With the exception of the US 1 Bypass in Portsmouth, alternates of U.S. Highways are signed as state routes. For example: Besides the US 1 Bypass, US 1 has two other alternates designated NH 1A and NH 1B. NH 11 has four alternates designated NH 11A, NH 11B, NH 11C and NH 11D. NH 25 has three alternates designated NH 25A, NH 25B and NH 25C. NH 101E in Hampton is an exception. Despite being an implied alternate of NH 101, NH 101E has never connected to NH 101 or any of its current or former alternates. Three instances of duplicated route numbers exist in New Hampshire: Two separate segments of highway are
