In 1955, President Dwight D. Eisenhower signed legislation creating the interstate highway system that links just about every major city in the United States. The very first stretch of this was an eight-mile stretch of I-70, which started in Missouri and ended in Topeka, Kansas.
Now, at 2,151 miles, I-70 runs from Baltimore, Maryland, to Provo, Utah. Since it was finished, Kansas and Missouri have been shaped by I-70.
