State Route 24 is a controlled-access highway at the intersection of Loop 202's southern leg (Santan Freeway) and Hawes Road, extending southeast near the Phoenix-Mesa Gateway Airport.

A portion of those funds are earmarked toward improvements of the county's regional freeway system, which experiences significant volumes of traffic in parts of the Phoenix Metropolitan Area.
