Its county seat and largest city is Salt Lake City, the state capital. The county was created in 1850. Salt Lake County is the 37th most populated county in the United States and is one of four counties in the Rocky Mountains to make it into the top 100.

Although, Utah County directly to the south has recently reached this threshold.

State Route 201 (SR-201) is an east–west expressway and freeway located in Salt Lake County in the U.S. state of Utah. Colloquially known by some as the 21st South Freeway, the route serves as an alternative to Interstate 80 (I-80) through Salt Lake City. From the western terminus of the route west of Magna, the highway heads east through Kennecott Copper property as an expressway before running through the western suburbs of Salt Lake City as a freeway. Shortly after the route returns on a surface route, SR-201 terminates on its eastern end at State Street.
Interstate 215 (I-215), also known locally as the Belt Route, is an auxiliary Interstate in the U.S. state of Utah that forms a three-quarters loop around Salt Lake City and many of its suburbs. The route begins at the mouth of Parley's Canyon at a junction with I-80 east of the city center, and heads south through the edge of the Salt Lake City metropolitan area's eastern suburbs of Millcreek, Holladay, and Cottonwood Heights. It continues west through Murray before turning north again, passing through the city's first-ring western suburbs of Taylorsville and West Valley City. It then enters North Salt Lake and Davis County for a short distance before reaching I-15 northwest of the city center.
State Route 68 (SR-68) is a state highway in the U.S. state of Utah. It is a major thoroughfare throughout the Wasatch Front as it runs north–south for 70.8 miles (113.9 km), linking US-6 near Elberta to US-89 in Woods Cross. The route intersects several major freeways and highways in the Salt Lake City metropolitan area including I-215, I-80, and I-15. The route is more commonly referred to as Redwood Road, after the street it is routed along throughout Salt Lake County. The highway is also routed for a short distance along 500 South and 200 West in Bountiful and Camp Williams Road in Utah County. The route is a surface street for its entire length.
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. It connects SR-201 in Magna to SR-209 in West Jordan in a span of 10.6 miles (17.06 km). It is known as 8400 West and Bacchus Highway throughout the route's course, in respect of north to south.
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. The route spans 22.47 miles (36.16 km) as it runs along portions of 12600 South, 12300 South, 900 East, and 700 East streets.
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 US state of Utah is 197.51 miles (317.86 km) long 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 Highway—US 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 Parleys Canyon and Summit County, travels through the mountain range, and intersects the eastern end of I-84 near Echo Reservoir before turning northeast toward 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.
State Route 152 (SR-152) is a state highway in the suburbs of Salt Lake City, Utah connecting SR-71 in Murray to I-215 and city-maintained Highland Drive in Cottonwood Heights, though for almost all of its length it forms the border between Murray and Holladay.

The Red Line is a light rail line on the TRAX system in the Salt Lake Valley of Utah operated by the Utah Transit Authority (UTA). It originally began operation in December 2001 as the peak-hour-only Sandy/University Line, running from the University of Utah south to Sandy Civic Center on the Blue Line. It was later rerouted to South Jordan and renamed the Red Line in August 2011, running as an all-day route. The current line runs from the University of Utah Medical Center in Salt Lake City through the south end of Downtown Salt Lake City, South Salt Lake, Murray, Midvale, West Jordan, and South Jordan to the University of Utah's South Jordan Medical Center in Daybreak.

State Route 190 (SR-190) or the Big Cottonwood Canyon Scenic Byway is primarily an east and west state highway and scenic highway in eastern Salt Lake County, Utah, United States, that begins at Interstate 215 (I-215), runs through Big Cottonwood Canyon, and ends at the Salt Lake and Wasatch county line.
State Route 195 (SR-195) was a north–south state highway in the U.S. state of Utah, following 2300 East in Salt Lake County. Formed in 1947, the route initially created a link from south of the University of Utah to future I-80. By the late-1960s, the route was extended south to Holladay, including an unbuilt portion of 2300 East between 2100 South and I-80. Following relinquishments of the route to Salt Lake City and Holladay, the road was deleted from the state highway system in 2007.
State Route 209 (SR-209) is a state highway in the U.S. state of Utah, following 9000 South and other east–west streets south of Salt Lake City. It connects the Bingham Canyon Mine with I-15 in Sandy and the ski areas of Little Cottonwood Canyon.
State Route 181 (SR-181) was a state highway in the U.S. state of Utah connecting SR-152 in Murray and Holladay north to SR-186 in Salt Lake City at its peak, the former being suburbs of the latter. The route was 6.9 miles (11.10 km) for thirty-eight years before being truncated in 2007 and decommissioned entirely later in the same year.
State Street is a wide 17.3-mile-long (27.8 km) street in Salt Lake County, Utah leading almost straight south from the steps of the Utah State Capitol Building, through Salt Lake City, South Salt Lake, Millcreek, Murray, eastern Midvale, Sandy, and northwestern Draper. Because it follows the most direct route from downtown Salt Lake City to the Point of the Mountain pass to Utah County, it was the undisputed main road south from Salt Lake City until Interstate 15 (I-15) was built to the west. It retains the U.S. Highway 89 designation for all but the northernmost seven blocks despite I-15's proximity. Due to its history as a route for long-distance travel, travel within the Wasatch Front region, and travel between the cities along the east side of the Jordan River, it has attracted a wide variety of retail and service businesses along its entire length, creating a nearly continuous commercial axis for the Salt Lake Valley.
3500 South MAX was a bus rapid transit (BRT) line in northwestern Salt Lake County, Utah, United States, operated by the Utah Transit Authority (UTA) that ran between Magna, West Valley City, and South Salt Lake.
