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 rapid transit and 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.
