Interstate 15 South

Traveling 29.39 miles, Interstate 15 angles across the northwestern corner of the Grand Canyon State connecting Mesquite, Nevada with St. George, Utah. The freeway winds through the Virgin River Gorge between Littlefield and the Utah state line. I-15 was constructed through the over 500 million year old gorge in phases from the 1960s into the early 1970s, opening to traffic in 1973. As part of construction, the Virgin River was re-channelled 12 times¹. The scenic section of freeway was once considered the most expensive Interstate highway constructed until the "Big Dig" in Boston (I-93) was completed in 2003.
