AZ 24

State Route 24 is the newest addition to the state highway system. The Gateway Freeway was originally only 1.4 miles long, just connecting Loop 202 to Ellsworth Road. However, on August 11, 2022, ADOT finished the SR 24 extension from Ellsworth Rd to Ironwood Drive, extending the length of the highway to 6 miles.

Length: 6 miles
Existed since: 2014
Current Route: Loop 202 in Mesa to Ironwood Drive in Pinal County
Major Junctions: Loop 202

Cool Features

SR 24 wins the title of the lowest-numbered state route in Arizona. SR 24 was the shortest state route in Arizona until the 2022 extension brought its distance up to 6 miles. The title of shortest state route now returns to SR 187 at 5.4 miles.

SR 24 was originally planned to be designated SR 802.
