Maine is the biggest state in New England, and most of it is trees. From the Turnpike traffic in the south to the two-hour woods run north of Bangor, here's how Maine's mile markers work, where they matter most, and how to see your exact one plus live road alerts in real time.

How Maine numbers its highways

Maine's mileposts count up from the south and west. On I-95, mile 0 sits at the New Hampshire line in Kittery, and the numbers climb roughly 300 miles north to Houlton on the Canadian border. The southern stretch of I-95 is the Maine Turnpike, a toll road with its own history — for years its exits were numbered sequentially rather than by mile, which confused plenty of out-of-state drivers. Today the roadside mileposts tell the real story, and mile marker data for every Maine highway is bundled into MileCheck and works offline.

The corridors people actually drive

  • I-95 is the spine — Kittery, Portland, Augusta, Bangor, then the long run north to Houlton.
  • I-295 splits off at Portland and hugs the coast through Brunswick before rejoining I-95.
  • US-1 follows the coast the whole way — Ogunquit, Camden, Bar Harbor traffic, and eventually Fort Kent.
  • US-2 crosses the state east to west through Bangor and the western mountains toward New Hampshire.

Where mile markers matter most: north of Bangor

South of Portland, an exit is never far away. North of Bangor is a different road entirely: roughly two hours of I-95 through unbroken woods, with long gaps between exits, few services, and stretches where your phone shows no bars. This is also serious moose country — collisions are a real hazard, especially at dawn and dusk. When something goes wrong up there, the green milepost on the shoulder is the one piece of location information that always works. Knowing yours before you need it is the whole point.

MP 0 · Kittery MP 100 MP 200 MP 302 · Houlton Portland Bangor · MP 182
I-95 runs about 302 miles through Maine, from Kittery at mile 0 past Portland and Bangor to Houlton at the Canadian border.

Winter, moose, and the North Woods

Maine winters are long, and the interstate north of Bangor gets snow, ice, and blowing conditions well into spring. Moose are the year-round wildcard — a full-grown one can total a car, and warnings and crash reports are given by route and mile marker. Add in the sheer distance between services up north, and Maine rewards drivers who keep an eye on both their milepost and the live conditions ahead.

Live Maine DOT alerts, in one place

MileCheck pulls live road alerts for Maine — closures, crashes, and construction — tied to the mile marker and route so you can see what's ahead of you before you're past the last exit for forty miles. Alerts refresh in real time, and the mile marker data underneath them works completely offline.

Everyday and emergency

Whether you're reporting a moose strike north of Island Falls, calling a tow on the Turnpike, or telling a friend which rest area to meet at, the mile marker is the location Maine's roads run on. MileCheck shows yours in real time, down to a tenth of a mile, with CarPlay and Android Auto support for the long hauls — even where the cell signal drops.
