# Transportation in Montana

Transportation in Montana comprises many different forms of travel. Montana shares a long border with Canada, hence international crossings are prevalent in the northern section of the state; there are 13 road crossings and one rail crossing.
As the fourth-largest state in the United States, journeying from one side to the other takes a long time. The state has an extensive network of roads, including state highways, Interstate highways and U.S. routes. Rail connections are also well-established and were an important method of transportation in Montana since the 1880s. Within individual cities, public transportation includes high-frequency bus services.
For travel further afield, 16 airports are operational within Montana. Bozeman Yellowstone International Airport in Gallatin County is the busiest airport and there are another seven major airports and eight minor ones providing commercial services.

## Roads

Montana has approximately 70,000 miles (110,000 km) of highways which start in, pass through or are entirely inside the state.
Prior to the creation of the state highway system and national numbered routes, a series of named auto trails traversed Montana and provided connections to other states. These included the Yellowstone Trail, Buffalo Trail, Vigilante Trail, and Green Trail.

### Interstate highways

1,198.8 miles (1,929.3 km) of the Interstate Highway System, which serve as a thoroughfare for long-distance road journeys, is contained within Montana, and all of these are maintained by the Montana Department of Transportation (MDT). Speed limits are generally 80 mph (130 km/h) in rural areas and 65 mph (105 km/h) in urban areas.
Montana's Interstate highways are as follows:
* I-15 – Monida, Sweetgrass
** I-115 – Butte, Downtown Butte
** I-315 – Great Falls, Downtown Great Falls
* I-90 – Mullan, Ranchester
* I-94 – Billings, Beach

### U.S. highways

Eleven national U.S. routes are within the state, as seen in the list below:
* US 2 – Troy, Bainville

In addition to these primary routes, Montana has a large number of state highways and smaller secondary routes. Speed limits on these roads are generally posted up to 70 mph (110 km/h) along rural areas.

### Vehicles

Vehicles themselves in Montana are required to display a Montana license plate on the back and front by the Department of Motor Vehicles. Eight different primary plate designs have been issued since drivers were required to register their cars in 1913.

## Bus service

The public transportation system in Montana is sparse as a whole, but several individual cities have local bus networks.

### Intercity bus service

Across Montana, the bus network does not have a large amount of intercity routes but Jefferson Lines goes to cities including Billings and Bozeman. Other carriers include Express Arrow.

### Local bus service

Some individual cities have their own bus network provided by a transit corporation.
Missoula is served by ASUM Transportation and Mountain Line; The Mountain Line public transit system runs twelve services around the city and the University of Montana. It is indirectly controlled by the local government which have appointed members onto the board of the transportation district.
Billings is served by MET Transit and Great Falls by Great Falls Transit.
All four agencies run routes with fairly frequent schedules allowing commuters quick movement around different areas of the cities.

## Rail transport

Historically, the state was traversed east-to-west by the main lines of three transcontinental routes: the Milwaukee Road, the Great Northern and the Northern Pacific.
All passenger rail in Montana is provided by Amtrak. The Empire Builder serves twelve stations along the northern tier of the state between North Dakota and Idaho. This daily long-distance train provides direct rail service westbound to Spokane, Seattle, and Portland, and eastbound to Fargo, St. Paul, Milwaukee, and Chicago. Southern Montana last saw passenger rail in 1979 when the North Coast Hiawatha was discontinued.
In terms of freight transportation, the BNSF Railway is the largest freight railroad with 1,983 miles (3,191 km) of track in Montana. The Class II Montana Rail Link operates 817 miles (1,315 km) of track leased from BNSF within the state. A number of other small railroad companies also exist.
