Interstate 70 is one of the major transcontinental highways in the United States, stretching approximately 2,568 miles from Baltimore, Maryland, to Utah’s Colorado border. As part of the Dwight D. Eisenhower System of Interstate Highways, I-70 connects several important cities, including Denver and Kansas City. It crosses seven states (Maryland, West Virginia, Ohio, Indiana, Illinois, Missouri, and Colorado) and provides travelers with access to notable landmarks such as the Great Smoky Mountains National Park and the Rocky Mountains. The highway serves both long-distance travel and regional traffic within these states, playing a significant role in the U.S. transportation infrastructure.
