Florida State Road 573 makes up the southernmost portion of Dale Mabry Highway, taking the route 1.90 miles south from the turn of U.S. 92 onto Gandy Boulevard to the Mac Dill Air Force Base main gate. The commercial arterial carries four lanes north from a roundabout with Marcum Street to Ballast Point Boulevard, and five lanes from there to U.S. 92.
Historically State Road 573 was previously designated as the southernmost section of State Road 685. This coincided with the designation of Interbay Boulevard west to Port Tampa City as Florida Secondary 685A.
The 1955 Florida Official Highway Map shows both Dale Mabry Highway south of U.S. 92 as SR 685 and Interbay Boulevard as SR 685A Today Interbay Boulevard is undesignated.
