The idea of constructing a direct transcontinental highway in the United States dates back to the early 20th century. The Federal Aid Road Act of 1916 played a significant role in the development of a national road network. However, it wasn’t until the Federal Aid Highway Act of 1956, also known as the National Interstate and Defense Highways Act, that the construction of Interstate 70 became a reality.

Construction of I-70 began in the late 1950s and continued throughout the following decades. The highway was designed to provide a high-speed and efficient route for both civilian and military purposes. It was primarily intended to promote economic growth, interstate commerce, and enhance national defense strategies.

Interstate 70 has witnessed several significant developments throughout its history, including the completion of the Eisenhower-Johnson Memorial Tunnel in Colorado, which is the highest vehicular tunnel in the world. Additionally, various sections of the highway have been widened, improved, and realigned to accommodate increasing traffic demands and enhance safety.
