Railroads have been an important method of transportation in Montana since the 1880s. Historically, the state was traversed by the main lines of three east-west transcontinental routes: the Milwaukee Road, the Great Northern, and the Northern Pacific. Today, the BNSF Railway is the state's largest railroad, its main transcontinental route incorporating the former Great Northern main line across the state. Montana RailLink, a privately held Class II railroad, operates former Northern Pacific trackage in western Montana.

In addition, Amtrak's Empire Builder train runs through the north of the state, stopping in the following towns: Libby, Whitefish, West Glacier, Essex, East Glacier Park, Browning, Cut Bank, Shelby, Havre, Malta, Glasgow, and Wolf Point.

Billings Logan International Airport is the busiest airport within a four state region (Montana, Wyoming, North and South Dakota) both in passenger boardings and air cargo. Montana's other major Airports include Bozeman Yellowstone International Airport (formerly Gallatin Field) Missoula International Airport, Great Falls International Airport, Glacier Park International Airport, Helena Regional Airport, Bert Mooney Airport and Yellowstone Airport. Eight smaller communities have airports designated for commercial service under the Essential Air Service program.

Historically, U.S. Route 10 was the primary east-west highway route across Montana, connecting the major cities in the southern half of the state. Still the state's most important east-west travel corridor, the route is today served by Interstate 90 and Interstate 94 which roughly follow the same route as the Northern Pacific. U.S. Routes 2 and 12 and Montana Highway 200 also traverse the entire state from east to west.

Montana's only north-south Interstate Highway is Interstate 15. Other major north-south highways include U.S. Routes 87, 89, 93 and 191. Interstate 25 terminates into I-90 just south of the Montana border in Wyoming.

Montana and South Dakota are the only states to share a land border which is not traversed by a paved road.
