The department was formed in 1969. It absorbed the powers of the State Road Department (SRD). The current Secretary of Transportation is Jim Boxold.  - State Road 874 ( SR 874 ) , named the Don Shula Expressway for its length , is an electronic toll road in southern Miami - Dade County , Florida . It extends 7 miles ( 11 km ) northeast from the Homestead Extension of Florida 's Turnpike ( HEFT ) in southwestern Kendall to the Palmetto Expressway ( SR 826 ) in Glenvar Heights , allowing traffic from the far south of Miami - Dade County and the Florida Keys to move to more central regions of metropolitan Miami and vice versa , bypassing communities along U.S. Route 1 , while also permitting local access to the Kendall district . The road , named in honor of the long - serving coach of the Miami Dolphins NFL team , is maintained and tolled by the Miami - Dade Expressway Authority ( MDX ) . Contrary to the numbering plan of Florida State Roads , SR 874 is signed north -- south .  - Florida's Turnpike Enterprise (FTE) is a business unit of the Florida Department of Transportation, employing private sector business practices to operate its 461-mile system of limited-access toll highways for the benefit of Florida's traveling public. The current Executive Director is Diane Gutierrez-Scaccetti.   - The Homestead Extension of Florida's Turnpike (HEFT), designated as the Ronald Reagan Turnpike and originally known as the West Dade Expressway or the West Dade Tollway, is a northsouth free-flow toll road southern extension of the similarly tolled Florida's Turnpike. The expressway runs around the west and north sides of the Greater Miami area, extending from U.S. Route 1 in Florida City (near Homestead) to the Turnpike mainline four miles north of the Golden Glades Interchange. The road carries the hidden designation of State Road 821 (SR 821). It was opened in stages between 1973 and 1974, after the main line of the Turnpike was completed, and is used by both commuters and travelers to the Florida Keys and Everglades National Park. Due to its path, it acts as a de facto outer beltway for Miami, with the Palmetto forming an inner beltway. Unlike other Florida's Turnpike Enterprise highways, it is treated as if it were part of Florida's Turnpike mainline by highway signs and exit numbers, despite its separate state road number.  - The Miami-Dade Expressway Authority (MDX) is an independent agency created in December 1994 by the State of Florida and the Miami-Dade County Commission.
