In the state of Maine, the Maine Department of Transportation (MaineDOT) has a system of numbered highways, defined as the "connected main highways throughout the state which primarily serve arterial or through traffic." As of 2006, 22,236 miles[1] of roadway are included in the highway system, including Interstate highways, U.S. Routes, state highways, and other urban and rural local roads.

Route types and funding[2][edit]

Interstate Highways[edit]

I-95 (ME).svg

Maine has one primary Interstate highway, I-95, within its borders, as well as four of its spurs: I-195, I-295, I-395, and I-495 (which is unsigned). All Interstate highways in Maine are part of the National Highway System and, as such, receive some degree of federal funding. All of these highways are freeways and are built under set standards for roadway design.

U.S. Numbered Highways[edit]

Maine contains two primary U.S. numbered highways: U.S. Route 1 and U.S. Route 2.

These routes are generally maintained and funded in the same manner as state routes, with these responsibilities falling to the MaineDOT.

State Routes[edit]

State routes in Maine are numbered and signed by the state, and by extension are also generally maintained and funded by the state, except in areas designated as "urban compact areas," defined by MaineDOT as "those in which the population according to the last United States census exceeds 7,500 inhabitants. Urban compact municipalities are also those in which the population according to the last United States census is less than 7,500 inhabitants but more than 2,499 inhabitants, and in which the ratio of people whose place of employment is in a given municipality to employed people residing in that same municipality according to the last United States census is 1.0 or greater." In this case, the section of road is the responsibility of the municipality.

State-aid highways[edit]

State-aid highways are roads chosen by the local municipality which serve as links between other state routes. Winter snow removal is the responsibility of the municipality, while other maintenance and funding is handled by the state, with the exception of urban compact areas.

Townways[edit]

Townways in Maine are classified as all highways that do not fall into one of the preceding categories. These roads are chosen, funded, and maintained by the towns, or the county in unorganized areas. The vast majority of highways in the state fall under this category. These also represent the closest thing to county roads in the state, as Maine does not have signed county roads as other states such as New York do.

Signage practices[edit]

State Routes[edit]

Maine's current state highway shield is a simple black-numeral-on-white-box design, identical to Massachusetts' state route shield design. Square shields are used for one- and two- digit routes, and elongated rectangular shields are used for three-digit routes.

Maine has three business state routes, indicated with a "Business" banner accompanying the route shield.

U.S. Highways[edit]

US 201A.svg

Maine uses standard shields for U.S. Routes, a white six-point shield on a black border. Square signs are used one- and two-digit routes and rectangular for three-digit routes. Maine also has two business U.S. Routes, indicated by banners complementing the corresponding route shields. Maine also has a U.S. Route 1 Bypass, indicated in the same way, with a bypass shield.

Interstate Highways[edit]

I-95 (ME).svg

Maine uses standard-size Interstate shields on its Interstate Highways. Many of Maine's Interstate shields contain the state name, and others do not. I-95 shields on the Maine Turnpike are generally accompanied by Maine Turnpike shields. The Falmouth Spur, designated I-495 in 2004, is unsigned.

Routes crossing state borders[edit]

New Hampshire Route 113B and New Hampshire Route 153 enter Maine. NH Route 113B is a loop of Maine's Route 113. Maine's Route 113 enters NH a couple of times even though it's still maintained by MDOT.
