US Route 20

U.S. Route 20 is an east–west United States highway. As the “0″ in its route number implies, U.S. 20 is a coast-to-coast route; however, because national park roads do not have signage for U.S. numbered highways, a gap exists through Yellowstone National Park and splits the route into two sections.
