U.S. Route 91 or U.S. Highway 91 is a 172.7-mile-long (277.9 km) north–south United States highway running from Brigham City, Utah, to Idaho Falls, Idaho, in the U.S. states of Idaho and Utah. Despite the "1" as the last digit in the number, US 91 is no longer a cross-country artery, as it has mostly been replaced by Interstate 15. The highway currently serves to connect the communities of the Cache Valley to I-15 and beyond. Prior to the mid-1970s, US 91 was an international commerce route from Long Beach, California, to the Canada–US border north of Sweetgrass, Montana. US 91 was routed on the main streets of most of the communities it served, including Las Vegas Boulevard in Las Vegas and State Street in Salt Lake City. From Los Angeles to Salt Lake, the route was built along the corridor of the Arrowhead Trail. A portion of the highway's former route in California is currently State Route 91.
State Route 186 (SR-186) is a state highway entirely within Salt Lake City, capital of the U.S. state of Utah. It forms a quarter-beltway connecting US-89 and I-15 leading north from Salt Lake City to I-80 leading east; as such, it effectively forms the missing (non-freeway) quarter of the I-215 belt route around the city, though it does not directly connect to I-215 at the north end. Despite this beltway role, the route passes through downtown Salt Lake City because downtown is built right up to the northern mountains surrounding City Creek Canyon. The portion of the route connecting downtown to I-80 is a high-capacity street heavily used by commuters, especially those travelling to the University of Utah or between downtown and eastern neighborhoods, but the portion on Capitol Hill north of downtown is much narrower and has sharp turns around the Capitol grounds. The roadway runs 9.34 miles (15.03 km) along Victory Road, Columbus Street, 300 North, State Street, 400 South, 500 South, and Foothill Drive.
Interstate 84 (I-84) is a part of the Interstate Highway System that links Portland, Oregon, to I-80 near Echo, Utah. The 117.38-mile-long (188.90 km) segment in the US state of Utah is the shortest of any of the three states the western I-84 passes through and contains the eastern terminus of the highway. I-84 enters Box Elder County near Snowville before becoming concurrent with I-15 in Tremonton. The concurrent highways travel south through Brigham City and Ogden and separate near Ogden-Hinckley Airport. Turing east along the Davis County border, I-84 intersects US Route 89 (US-89) and enters Weber Canyon as well as Morgan County. While in Morgan County, I-84 passes the Devil's Gate-Weber Hydroelectric Power Plant and Devil's Slide rock formation. Past Morgan, the highway crosses into Summit County, past the Thousand Mile Tree before reaching its eastern terminus at I-80 near Echo.
