The SR 91 mainline runs roughly 265 miles (426 km), from its southern terminus at an interchange with Interstate 95 (I-95) in Miami Gardens to an interchange with I-75 in Wildwood at its northern terminus. The Homestead Extension of Florida's Turnpike continues from the southern end of the mainline for another 48 miles (77 km) to US Highway 1 in Florida City. The slogan for the road is "The Less Stressway". The mainline opened in stages between 1957 and 1964, while the extension was completed in 1974. The turnpike runs through Miami, Fort Lauderdale, and West Palm Beach, where it parallels I-95, and through Orlando, where it crosses I-4.

The Homestead Extension of Florida's Turnpike (HEFT), designated as unsigned State Road 821 (SR 821), is the southern extension of Florida's Turnpike, a toll road in the U.S. state of Florida maintained by Florida's Turnpike Enterprise (FTE). Spanning approximately 48 miles (77 km) along a north–south axis, it supplements the 265-mile (426 km) mainline to form the complete 309-mile (497 km) turnpike.

The route also passes through the cities of Fort Lauderdale, West Palm Beach, Port St. Lucie, Titusville, and Daytona Beach.
Interstate 75 (I-75) is a part of the Interstate Highway System that runs from the Hialeah–Miami Lakes border, a few miles northwest of Miami, to Sault Ste. Marie in the Upper Peninsula of Michigan. I-75 begins its national northward journey near Miami, running along the western parts of the Miami metropolitan area before traveling westward across Alligator Alley, resuming its northward direction in Naples, running along Florida's Gulf Coast, and passing the cities of Fort Myers, Punta Gorda, Venice, and Sarasota. The freeway passes through the Tampa Bay area before turning inward toward Ocala, Gainesville, and Lake City before leaving the state and entering Georgia. I-75 runs for 471 miles (758 km) in Florida, making it the longest Interstate in the state and also the longest in any state east of the Mississippi River. The Interstate's speed limit is 70 mph (110 km/h) for its entire length in Florida.
There have been plans in Florida for expressways, but some were never constructed due to financial problems, community opposition and environmental issues.
