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 Despite the "1" as the last digit in the number, US 91 is no longer a cross-country artery, as it has mostly been replaced by Interstate 15.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 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.

It is Utah's primary and only north–south interstate highway, as the vast majority of the state's population lives along its corridor; the Logan metropolitan area is the state's only Metropolitan Statistical Area through which I-15 does not pass. In 1998, the Utah State Legislature designated Utah's entire portion of the road as the Veterans Memorial Highway.
U.S. Route 89 in the U.S. state of Utah is a north-south United States Highway spanning more than 502 miles (807.891 km) through the central part of the state, making it the longest road in Utah.

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.
5600 West BRT is a proposed bus rapid transit (BRT) line in western Salt Lake County, Utah, United States, that will be operated by the Utah Transit Authority (UTA) and will run along 5600 West (SR-172). Initially, it will only run along a short segment almost entirely within West Valley City, with a connection to Downtown Salt Lake City. However, it will eventually run from South Jordan to the Salt Lake City International Airport.) It is the fifth of several BRT lines that UTA either operates or has planned for in Utah County and the Salt Lake Valley. UTA's BRT is described by UTA as "light rail on rubber tires". While it was initially planned for phase 1 of the project to be completed in 2015, the project is currently stalled.
