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.
State Route 111 (SR-111) is a state highway in the U.S state of Utah that runs north–south across the west side of the Salt Lake Valley in Salt Lake County.

State Route 71 (SR-71) is a state highway completely within the Salt Lake City metropolitan area in the northern portion of the US state of Utah. It runs from SR-154 in the southwest side of the city to SR-186 in Downtown Salt Lake City.

State Route 198 is a highway completely within Utah County in northern Utah that connects Santaquin to Spanish Fork via Payson and Salem. The route runs 16 miles (26 km).

U.S. Route 6 (US-6) is an east–west United States Numbered Highway through the central part of the U.S. state of Utah. Although it is only about 40 miles (64 km) longer than US-50, it serves more populated areas and, in fact, follows what had been US-50's routing until it was moved to follow Interstate 70 (I-70) in 1976. In 2009, the Utah State Legislature named part of the route the "Mike Dmitrich Highway", named after the Utah state senator, which generated controversy, as the state of Utah had previously joined with all the other states through which US-6 passes in naming all of US-6 the Grand Army of the Republic Highway.
