Major Freeway Systems of the Western United States

Utah's transportation system includes 43,155 miles of federal, state and local highways and roads. Of that total, 14% is classified as urban mileage. The three most important highways within the state are I-15, which runs north to Idaho and south into Arizona; I-70, an east-west route through the central part of the state and I-80, a coast-to-coast artery that runs through the Salt Lake City area. These three interstate highways are important to the efficient transportation of goods and materials throughout Utah.

Other important links in the interstate system are I-84 northbound into the Pacific Northwest, and I-215, the Salt Lake County belt route.
