{{Main|Interstate 70 in Utah}}
I-70 begins at an [[interchange (road)|interchange]] with [[Interstate 15|I-15]] near [[Cove Fort]]. Heading east, I-70 crosses between the Tushar and [[Pahvant Range|Pahvant]] ranges via [[Clear Creek Canyon]] and descends into the [[Sevier Valley]], where I-70 serves [[Richfield, Utah|Richfield]], one of two towns of more than a few hundred people along I-70's path in Utah. The second town with more than a few hundred people served by I-70 is [[Salina, Utah|Salina]]. Upon leaving the valley near Salina, I-70 crosses the {{convert|7923|ft|m|adj=on}} Salina Summit and then crosses a large geologic formation called the [[San Rafael Swell]].

Prior to the construction of I-70, the swell was inaccessible via paved roads and relatively undiscovered. Once this {{convert|108|mi|km|adj=on}} section was opened to traffic in 1970, it became the longest stretch of Interstate Highway with no services and the first highway in the U.S. built over a completely new route since the [[Alaska Highway]].<ref name="utah new">{{cite web |title=Interstate 70 |url=http://members.aol.com/utahhwys/rte070.htm |url-status=usurped |archive-url=https://web.archive.org/web/20070312085507/http://members.aol.com/utahhwys/rte070.htm |archive-date=March 12, 2007 |access-date=January 30, 2007 |work=Utah Highways |language=en-US}}</ref>{{unreliable source?|failed=y|date=November 2013}} It also became the longest piece of Interstate Highway to be opened at one time.<ref name = "why cove fort"/> Although opened in 1970, this section was not formally complete until 1990, when a second steel arch bridge spanning Eagle Canyon was opened to traffic.

Since I-70's construction, the swell has been noted for its desolate beauty. The swell has since been nominated for [[List of national parks of the United States|national park]] or [[National monument (United States)|national monument]] status on multiple occasions. If the swell is granted this status, it arguably would be the first time a national park owes its existence to an Interstate Highway. Most of the exits in this span are rest areas, brake check areas, and [[runaway truck ramp]]s with few traditional freeway exits.

I-70 exits the swell near [[Green River, Utah|Green River]]. From Green River to the Colorado state line, I-70 follows the southern edge of the [[Book Cliffs]].
