New Hampshire Highway System
Encyclopedia
The New Hampshire Highway System is the public roads system of the U.S. state
of New Hampshire
containing approximately 17029 miles (27,405.5 km) maintained by the New Hampshire Department of Transportation
. All public roads in the state are called "highways", thus there is no technical distinction between a "road" or a "highway" in New Hampshire.
Highways assigned a number by the NHDOT are officially known as "New Hampshire Route X", often abbreviated "NH Route X" or simply "Route X".
Many minor state highways are not assigned numbers, only local names.
In March 2011, New Hampshire ranked amongst the top ten "Best" states in the American State Litter Scorecard, for overall effectiveness and quality of its public space cleanliness—-primarily roadway and adjacent litter--from state and related debris removal efforts.

highways; and 505 miles (812.7 km) of non-interstate and non-turnpike highways.

In addition, Maine State Route 113
crosses in and out of New Hampshire along two short stretches. It remains under MaineDOT maintenance along these stretches.
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. Route 113B) are signed with the parent highway's number over the letter of the alternate. New Hampshire also has one 'bypass' state route, Route 28 Bypass, which is marked with a standard Route 28 shield, except with the word 'BYPASS' over the numeral. Route 101 has its own business route, and its alternate, Route 101A, has its own bypass, but these routes are very poorly signed, if only on guide signs.

New Hampshire uses the standard issue U.S. Route shield, a six-point white shield over a black square background. New Hampshire does not use elongated route shields for U.S Routes, except on the occasional guide sign from a freeway. Alternates of U.S. Routes in New Hampshire are signed as state routes, with two exceptions: U.S. Route 1 Bypass and U.S. Route 3 Business. US-1 Bypass is signed in a similar fashion to Route 28 Bypass, a standard US-1 shield with the word 'BY-PASS' over the numeral. US-3 Business is unsigned, as it is completely overlapped by other routes.
New Hampshire uses standard size Interstate shields for its two-digit Interstate highways. Elongated shields were not initially used for auxiliary Interstates, but such shields are appearing on newer signage. New Hampshire no longer uses its state name on Interstate shields, but older signs with the state name are still prevalent.

. 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. Route 113B) are signed with the parent highway's number over the letter of the alternate. New Hampshire also has one 'bypass' state route, Route 28 Bypass, which is marked with a standard Route 28 shield, except with the word 'BYPASS' over the numeral. Route 101 has its own business route, and its alternate, Route 101A, has its own bypass, but these routes are very poorly signed, if only on guide signs.

Interstate highways
Route concurrencies
New Hampshire has an unusual way of signing route concurrencies. Rather than separate shield assemblies for each route, concurrencies are signed on green signs, similar to those found on freeway guide signs. These signs are also used for signing junctions with other routes, regardless of whether there is a concurrency. These particular sign assemblies are, however, lacking in cities.Numbered state highways
