North Rim of Grand Canyon National Park. Utah The first city in Utah along either US 89 or US 89A is Kanab where the two routes re-unite. From Kanab US 89 proceeds north passing by Zion National Park, Cedar Breaks National Monument, and Bryce Canyon National Park. It eventually enters Sevier County and the Sanpete Valleys. The highway then passes by Thistle, a ghost town that was destroyed by a lake resulting from a landslide in 1983. The highway then enters the Wasatch Front where US 89 becomes State Street, the main street for many cities in Utah and Salt Lake Counties. The highway is also often in the shadows of Interstate 15 (I-15) during its route along the Wasatch Front. US 89 runs concurrently with I-15 from Bountiful to Farmington, where it departs and runs at the base of the Wasatch Mountains until it reaches Ogden. In Ogden, the highway is Washington Boulevard. From Ogden the highway runs north until it meets US 91 at Brigham City, where it turns east to serve Cache Valley and Logan, concurrent with US 91. In Logan, US 89 forms the southern portion of Main Street before splitting off to the east, passing by the campus of the Utah State University. The highway next proceeds up Logan Canyon to Bear Lake where the highway exits Utah. Two sections of US 89 in Utah have been designated Scenic Byways. The Kanab to Mt. Carmel and Long Valley Scenic Byway is a designated Utah Scenic Byway. The segment from Logan to Bear Lake is designated as the Logan Canyon Scenic Byway by the National Scenic Byways project. The section of US 89 in Utah, other than concurrencies with I-70, I-15, US 6, and US 91, is defined in the Utah Code Annotated § 72-4-114(8). Utah is dominated by the Colorado Plateau. Along US 89 are Zion National Park, Bryce Canyon National Park, and Cedar Breaks National Monument. Although not readily adjacent to US 89, Capitol Reef National Park is accessible from US 89. US 89 leaves northern Utah well north of Salt Lake City and Timpanogos Cave National Monument and the Golden Spike National Historic Site. Idaho In Idaho, the highway partially circumnavigates Bear Lake, which straddles the Utah–Idaho state line. Wyoming In Wyoming, US 89 passes through many scenic sites including Grand Teton National Park, the Jackson Hole valley, the Snake River Canyon, and
