Interstate 80 marker

Interstate 80 (I-80) is a part of the Interstate Highway System that runs from San Francisco, California, to Teaneck, New Jersey. The portion of the highway in the U.S. state of Utah is 196.35-mile-long (315.99 km), through the northern part of the state. From west to east, I-80 crosses the state line from Nevada in Tooele County and traverses the Bonneville Salt Flats—which are a part of the larger Great Salt Lake Desert. It continues alongside the Wendover Cut-off—the corridor of the former Victory HighwayU.S. Route 40 (US-40) and the Western Pacific Railroad Feather River Route. After passing the Oquirrh Mountains, I-80 enters the Salt Lake Valley and Salt Lake County. A short portion of the freeway is concurrent with I-15 through Downtown Salt Lake City. At the Spaghetti Bowl, I-80 turns east again into the mouth of Parley's Canyon and Summit County, travels through the mountain range and intersects the eastern end of I-84 near Echo Reservoir before turning northwest towards the Wyoming border near Evanston. I-80 was built along the corridor of the Lincoln Highway and the Mormon Trail through the Wasatch Range. The easternmost section also follows the historical routes of the First Transcontinental Railroad and US-30S.
