Interstate 70 (I-70) was constructed in phases, with its initial segments opening in the 1950s. The highway was officially designated as part of the Interstate Highway System in 1956, and it was largely completed by the early 1980s. The project aimed to create a major east-west route across the United States, running from Baltimore, Maryland, to Cove Fort, Utah.
