The 37-mile State Route 85 corridor – which provides a major north-south connection between Interstate 10 and Interstate 8 – serves an important role in both interstate travel and intrastate travel between the Phoenix region and the growing communities of Gila Bend and Yuma. It also allows traffic using I-10 to bypass the urban core of the Phoenix region.

State Route 85 is classified as a rural arterial highway in the State Highway System and a principal arterial highway on the National Highway System.

The highway serves as a major link between the Phoenix metropolitan region and the San Diego metropolitan region, as well as an interstate trucking route to access the major international ports in the Los Angeles region. SR 85 and Business 8 are also designated sections of the future proposed Canada-America-Mexico (CANAMEX) trade route. More . . .
