Billings is at the junction of two interstate highways: I-90, connecting the city with the Pacific Northwest and the southern Rocky Mountain states; and I-94, providing a link with the midwestern states. U.S. 87, 310, and 212 also meet in Billings.
Billings is served by regional and interstate bus lines. As of 2005 there was no regular passenger rail service in or out of Billings.
Billings Metropolitan Transit operates 17 routes within the city. In 2004 Federal funds were authorized for the purchase of 16 new buses over a 3-year period. Auto traffic on major thoroughfares is light compared to most metropolitan areas. The downtown area is laid out in a grid pattern with numbered streets.
