Travel directions

I-8 at Yuma.

At the town of Yuma, Interstate 8 in California crosses the Colorado River and enters the state of Arizona. The highway first leads through low-lying agricultural areas near Yuma, then through the Yuma suburbs that lie in the desert. To the east, I-8 leads through a small mountain area. I-8 then heads east through virtually uninhabited desert, parallel to the Gila River. The highway has 2×2 lanes and crosses few other major roads until Gila Bend. At Gila Bend, one crosses State Route 85, which leads to Phoenix. I-8 runs over 60 miles south of Phoenix and is not part of the metropolitan area. The easternmost part of the route has some agricultural land again, after which I-8 at Casa Grande on Interstate 10ends, about halfway between Phoenix and Tucson.

History

I-8’s predecessor was US 80, which began in San Diego and was the southernmost east-west US Highway in the southwestern United States. US 80 was an important connection from San Diego to the interior and was paved in the late 1920s and early 1930s, especially during the 1929-1931 period.

US 80 has largely been converted to Interstate 8, leaving no two parallel routes on much of the route. The widening to freeway began in the late 1950s and progressed steadily through the 1960s. By 1971, I-8 was nearly completed, with the final sections opening at Yuma and Casa Grande. In 1977, US 80 was dropped from the route, which was then numbered only as I-8.
