This connector route between the Western Express Route and the Southern Tier Route is a prime example of the vast and beautiful American West. It also connects the magnificent Zion National Park and both sides of Grand Canyon National Park. From the Western Express Route, it offers the opportunity to access Zion National Park and the north rim of the Grand Canyon. From the Southern Tier Route, it is 185 miles to reach the south rim of the Grand Canyon.
