U.S. Route 89 (US 89) is a part of the U.S. Highway System that travels Flagstaff, Arizona, north to the Canadian border; broken into two segments by Yellowstone National Park where unnumbered park roads serve as a connector. In the state of Wyoming, it extends approximately 156 miles (251 km) from the Idaho state line near Geneva, Idaho to the southern entrance of Yellowstone National Park. US 89 passes through many scenic sites including Grand Teton National Park, the Jackson Hole valley, the Snake River Canyon, and Star Valley and is the backbone visitor highway for two U.S. National Parks.
