Interstate 70
Interstate 70 (abbreviated I-70) is a long interstate highway in the United States that runs from Interstate 15 about a mile from Cove Fort, Utah, to a Park and Ride in Baltimore, Maryland. It was the first Interstate Highway Project started in the United States. I-70 approximately traces the path of U.S. Route 40 (and also the old National Road) east of the Rocky Mountains. West of the Rockies, the route of I-70 was cobbled together from a variety of sources.
The construction of I-70 in Colorado and Utah is considered an engineering marvel where the route passes through the Eisenhower Tunnel, Glenwood Canyon, and the San Rafael Swell. The Eisenhower Tunnel is the highest point along the Interstate highway system with an elevation of 11,158 feet (3,401 m).
The sections of the interstate in Missouri and Kansas have laid claim to be the first interstate in the United States. The final piece of Interstate 70 was opened to traffic at Glenwood Canyon in 1992. Most people considered this to be the last piece of the Interstate Highway System as originally planned to be opened.
