Alligator Alley is a 78 mile section of Interstate 75 in South Florida connecting the southwestern and southeastern coastal areas of Florida. It was originally constructed during the late 1960s as a two-lane, controlled access toll road and was known in the original bond documents as “Everglades Parkway.” During the late 1970s and early 1980s, the Florida Department of Transportation (FDOT) completed construction of the Interstate 75 corridor on the west coast between Tampa and Naples. From 1986 to 1992, Alligator Alley was also widened to four-lanes and made a limited-access, tolled, interstate facility (I-75), now part of the Florida Intrastate Highway System (FIHS).
Tolls on Alligator Alley are collected at mainline plazas on either end (westbound tolls collected on the east end; eastbound tolls collected on the west end). Two toll-free interchanges are located along the Alley, at U.S. 29 and C.R. 833. The accompanying map illustrates these features as well as present toll rates for cash and for SunPass, the state’s pre-paid electronic toll collection system.
During fiscal year (FY) 2007, approximately 8.3 million toll transactions on Alligator Alley produced approximately $23.5 million in revenues. Operations and maintenance costs for that same period were approximately $6.1 million.
