Interstate 15 (I-15) runs north–south in the U.S. state of Utah through the southwestern and central portions of the state, passing through most of the state's population centers, including St. George and those comprising the Wasatch Front: Provo–Orem, Salt Lake City, and Ogden–Clearfield. 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.
