State Route 84
Arizona State Route 84 is a short connecting road between Casa Grande and Interstate 8. First designated as a state highway in 1927, SR 84 was subsequently extended and truncated over the years.
The original highway was designated in 1927 between Casa Grande and Tucson, paralleling the Southern Pacific Railroad line. SR 84 was extended west to Gila Bend in 1930, effectively turning it into a shortcut for through traffic between San Diego and Tucson traveling U.S. 80.
In time, SR 84 would become the primary thru route, which led to the demise of most of the road. When the route for Interstate 10 was laid out between Phoenix and Tucson, it followed SR 84 between Casa Grande and Tucson, as the route was shorter than U.S. 80 through Florence. Interstate 8 was designed to overlay the rest of SR 84.
In 1966, Interstate 10 between Eloy and Tucson was completed, truncating SR 84 at Eloy. The original road exists as a frontage road today.
In 1974, SR 84 was decommissioned between Gila Bend and Interstate 8 at Exit 151, the current end point.
In 1997, SR 84 between Downtown Casa Grande and SR 87 was decommissioned. Today, the signed route travels between Interstate 8 and Downtown Casa Grande, and the unsigned route travels between SR 87 and Interstate 10.
