Interstate 70

Category for Interstate 70

Interstate 70 is one of the nation’s primary east–west highways, stretching approximately 2,171 miles across the United States from Cove Fort, Utah, to a major terminus in Baltimore, Maryland. It serves as a vital transportation corridor through the heart of the country, traversing diverse landscapes including the Rocky Mountains, the Great Plains, and the industrial Midwest. I-70 plays a crucial role in both freight movement and passenger travel, linking dozens of urban centers and connecting with numerous other major interstates along its route.

The western end of I-70 begins in the rugged terrain of central Utah, where it cuts through remote and scenic areas before climbing into the Colorado Rockies. The Eisenhower–Johnson Memorial Tunnel, one of the highest vehicular tunnels in North America, is a major engineering landmark along this stretch. Continuing east, the highway descends into Denver, then pushes through the plains of Kansas and Missouri, intersecting with cities like Topeka, Kansas City, and St. Louis.

In the eastern portion of its route, I-70 winds through Illinois, Indiana, and Ohio, providing a direct link between Indianapolis and Columbus. From there, it passes through Pennsylvania’s Appalachian region and connects to the Baltimore metropolitan area via a relatively short segment in Maryland. Notably, the eastern terminus near Baltimore ends at a park-and-ride facility, due to the cancellation of the planned extension through the city. This leaves I-70 one of the few major interstates without a direct connection to its final urban core.
