Originally, the Salt Lake Valley was inhabited by the Shoshone, Paiute, Goshute and Ute Native American tribes.
 At the time of the founding of Salt Lake City the valley was within the territory of the Northwestern Shoshone, who had their seasonal camps along streams within the valley and in adjacent valleys.
 One of the local Shoshone tribes, the Western Goshute tribe, referred to the Great Salt Lake as "Pi'a-pa", meaning "big water", or "Ti'tsa-pa", meaning "bad water".
 The land was treated by the United States as public domain; no aboriginal title by the Northwestern Shoshone was ever recognized by the United States or extinguished by treaty with the United States.
 Father Silvestre Vélez de Escalante, a Spanish Franciscan missionary is considered the first European explorer in the area in 1776, but only came as far north as Utah valley (Provo), some 60 miles south of the Salt Lake City area.

 U.S. Army officer John C. Frémont surveyed the Great Salt Lake and the Salt Lake Valley in 1843 and 1845.
 The Donner Party, a group of ill-fated pioneers, traveled through the Great Salt Lake Valley a year before the Mormon pioneers.
 This group had spent weeks traversing difficult terrain and brush, cutting a road through the Wasatch Mountains, coming through Emigration canyon into the Salt Lake Valley on August 12, 1846.
 This same path would be used by the vanguard company of Mormon pioneers, and for many years after that by those following them to Salt Lake.

State Street is a wide 17.3 mi street in Salt Lake County, Utah leading almost straight south from the steps of the Utah State Capitol Building, through Salt Lake City (including Downtown Salt Lake City), South Salt Lake, western Millcreek Township, Murray (including the Murray Downtown Historic District), eastern Midvale, Sandy (including the Sandy Historic District and Downtown 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 was built to the west (but closely paralleling it).
 It retains the US Highway 89 designation for all but the northernmost seven blocks (which are part of State Route 186 instead) 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.
