Interstate 75 (I-75) is a part of the Interstate Highway System and 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 South Florida before traveling westward across Alligator Alley (also known as Everglades Parkway), resuming its northward direction in Naples, running along Florida's Gulf Coast, passing the cities of Fort Myers, Punta Gorda, Venice, Sarasota, and the Tampa Bay Area, before turning inward towards 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 any state east of the Mississippi River. The interstate maintains a speed limit of 70 mph (110 km/h) for its entire length in Florida.
The portion of I-75 from Tampa northward was a part of the original 1955 Interstate Highway plans, with I-75's southern terminus at I-4's current western terminus. The interstate was extended south to Miami in 1968 after massive growth in Southwest Florida, which resulted in I-75 being realigned to travel on the eastern fringes of the Tampa Bay area, and the last portions of the highway was opened in 1993.
For FDOT inventory purposes, it is designated as State Road 93 (SR 93) for most of its length in Florida (with exception to the Tampa Bay area, where SR 93 follows I-275, while SR 93A travels with I-75 in the latter's bypass of the area).
As it curves around the border of Miami Lakes, I-75 serves some of the western fringes of South Florida as an eight-lane highway. After an exit with SR 860, I-75 has a southbound interchange with the Homestead Extension of Florida's Turnpike before crossing into Broward County. There, it continues through the western suburbs of Pembroke Pines, Weston, Miramar, Davie, and Southwest Ranches.
At the junction of SR 869 (Sawgrass Expressway) and I-595, I-75 (while maintaining its south–north status) enters a west–east trajectory as it crosses the Everglades by way of Alligator Alley, a toll road which was constructed originally as a two-lane highway before it was converted to a four-lane highway meeting Interstate Highway standards. At this point, I-75 loses a lane in each direction, heading west, losing another lane west of the U.S. Route 27 (US 27) interchange, the last interchange before the toll plaza.
The Everglades and Southwest Florida
The Alligator Alley section west of Fort Lauderdale, Florida and east of Naples is due west–east and is one of only two sections of I-75 that are tolled (the other is the Mackinac Bridge). There are only two interchanges along the 75 mile tolled portion of Alligator Alley in addition to two rest areas and a number of scenic outlook points as it crosses the Florida Everglades. I-75 enters Collier County along Alligator Alley just west of the Snake Road exit (exit 49) and passes through the Big Cypress National Preserve between the Collier County border and State Road 29 (exit 80). There are a number of small bridges along Alligator Alley to allow wildlife to pass under the freeway especially along the Florida Panther National Wildlife Refuge east of SR 29. Extensive fencing also prevents wildlife from crossing traffic.
Once near Naples at County Road 951 (Exit 101), I-75 makes a sharp turn north resuming its south–north trajectory and gains a third lane each way as it parallels Florida's west coast. As it continues north, I-75 passes near Bonita Springs, Fort Myers, Punta Gorda, Port Charlotte, Venice, Sarasota, and Bradenton, before reaching the Tampa Bay Area metropolis consisting of Tampa and St. Petersburg.
Tampa Bay area
In Ellenton, I-275 splits from I-75 to serve St. Petersburg and Pinellas County via the Sunshine Skyway Bridge and Tampa via the Howard Frankland Bridge. I-75 parallels the eastern shore of Tampa Bay as a bypass route of the Tampa Bay Area, as it passes by the communities of Brandon, Temple Terrace, and New Tampa. Two expressways access downtown Tampa from I-75: the Lee Roy Selmon Expressway (SR 618) and I-4. Within the Tampa Bay Metropolitan Area, many interchanges are far more complex than mere diamond, cloverleaf, or even SPUI interchanges. Aside from the large turbine interchange with I-4 (Exit 261), there are interchanges with Fowler Avenue (Exit 265) and Fletcher Avenue/Morris Bridge Road (Exit 266) that contain both loops and flyovers. A flyover ramp was built from southbound Bruce B. Downs Boulevard (Exit 270) to southbound I-75.
At the Hillsborough–Pasco county line (south of SR 56 (Exit 275)), I-275 rejoins I-75 (at Exit 274, southbound only) and I-75 changes into a southwest–northeast trajectory as it passes through Pasco, Hernando, and Sumter Counties where it runs through parts of the Withlacoochee State Forest on its way to the junction with Florida's Turnpike. Widened median segments exist in Northern Pasco County, Hernando County, and in Sumter County north of County Road 476-B (Exit 309). Some of these median segments are actually considered part of the Withlacoochee State Forest itself. The Withlacoochee State Trail runs beneath I-75 between US 98/SR 50 (Exit 301) and the Hernando–Sumter County line, where it also crosses over the Withlacoochee River.
After Florida's Turnpike (accessible from southbound I-75 only), I-75 changes into a general southeast–northwest trajectory, which is sustained to the Georgia state line and beyond. I-75 passes beneath the Cross Florida Greenway, which contains a land bridge built across the highway in 2001 between Exits 341 and 350, before entering the City of Ocala, and passing by the cities of Gainesville and Lake City and crosses I-10 at an interchange before entering the state of Georgia, near Valdosta.
I-75 runs closest to US 41 except between Tampa and High Springs. It runs closer to US 301 between Ellenton and Temple Terrace, and again from Dade City to Sparr. From Belleview to Lake City it runs closest to US 441.
- From southern terminus to I-595 (exit 19), four lanes each way
- Between I-595 to US 27 (exit 23), three lanes each way
- Between US 27 and Golden Gate Parkway (exit 105), two lanes each way
- Between Golden Gate Parkway and SR 80 (Palm Beach Boulevard, exit 141), three lanes each way
- Between SR 80 (Palm Beach Boulevard) and River Road (exit 191), two lanes each way, but gradually being widened to three lanes each way
- Between River Road and SR 582 (Fowler Avenue, exit 265) three lanes each way except through Riverview and part of Brandon where it is up to five lanes each way
- Between SR 582 (Fowler Avenue) and Florida's Turnpike (exit 328), two lanes each way, but gradually being widened to three lanes each way
- Between Florida's Turnpike and Georgia state line three lanes each way
Originally, I-75 was planned to be built to Tampa, where it would terminate at I-4 (at the current interchange between I-4 and I-275). Construction of the original route from the Georgia border to Tampa via Gainesville and Ocala lasted through most of the 1960s and was completed by 1969. At this point, I-4 continued west along what is now I-275 over the Howard Frankland Bridge into St. Petersburg.
Extension to Miami
Due to major growth in Southwest Florida (particularly Fort Myers and Naples), Florida's state government proposed to build a "West Coast Turnpike" in the mid-1960s from the Tampa Bay area, which would have originated near Lutz and run south to Naples, where it would connect to Alligator Alley (connecting Naples and Fort Lauderdale). Plans for the West Coast Turnpike (which would have been tolled) were cancelled in 1968, when it was announced that the Federal Government would pay 90% towards extending I-75 to Naples and eventually South Florida.
In preparation for the extension, I-75's designation was extended along I-4 into St. Petersburg by the end of 1969, and I-4's designation was truncated to its current terminus by 1971. The initial plan was to have I-75 continue from I-4's former terminus in St. Petersburg south over the Sunshine Skyway Bridge, where it would continue to Naples closely following the West Coast Turnpike's original plans. From Naples, I-75 was planned to run along the Tamiami Trail (U.S. Highway 41) across the Everglades to just east of the Palmetto Expressway where it would continue along the Dolphin Expressway and terminate at I-95 in Downtown Miami.
Once the Miami extension was planned in 1968, construction began on a bypass route east around Tampa Bay (which would also have been part of the West Coast Turnpike). The bypass was initially planned to be designated I-75E, and was to split from I-75 near Wesley Chapel. However in 1972, it was determined that maintaining the main route of I-75 through Downtown Tampa would eventually require major improvements to the existing infrastructure to handle through traffic. As a result, it was decided that I-75's route would follow I-75E bypassing downtown, the first of two major changes to the plans for the Miami extension. The route through downtown Tampa and St. Petersburg would be re-designated I-275.
The other major change made to the initial plan was the routing across the Everglades. Due to environmental concerns of upgrading the Tamiami Trail and the fact that the Dolphin Expressway was not built to Interstate standards, the decision was made in 1973 to shift I-75's proposed route to cross the Everglades along Alligator Alley, which at the time was in greater need of being upgraded. By using this route, I-75 would run to the proposed I-595, where it would turn south to Miami through the western suburbs of Weston and Pembroke Pines. It was still planned to continue east to I-95, but due to local opposition, I-75 was not built past its current terminus at the Palmetto Expressway in Hialeah.
The Miami extension was built mostly from the mid 1970s to the late 1980s. It was completed between Wesley Chapel and Naples by 1986, and portions in the western suburbs of Miami were also opened at this time. The final segment to be completed was the upgrade of the original Alligator Alley to interstate standards. The entire freeway was complete by 1992.
Alligator Alley was originally built by H. L. Mills Construction Company as a two-lane tollway connecting the two coasts of Florida, as a part of State Road 84 (which is currently the hidden designation of the highway). The alley, also known as Everglades Parkway, opened for traffic on February 11, 1968 and it has been called the most controversial roadway ever built in Florida. The name "Alligator Alley" was given by the American Automobile Association while it was planned since they believed it would be useless to cars, merely an "alley for alligators". However, as alligators often frequent the waterways beside the road, and occasionally the road itself, the nickname has developed a somewhat literal meaning. The name was officially adopted in 1966.
As a two-lane road, Alligator Alley was very dangerous as it was notorious for high-speed accidents and the need to improve it was a factor in the decision to reroute I-75 onto it. In preparation for the I-75 extension, the alley was rebuilt as a four-lane highway between 1986 and 1992, with many bridges designed to let water and wildlife pass underneath. This helped to reduce the environmental impact of the highway somewhat, especially upon the severely endangered Florida panther. Alligator Alley was the last section of I-75 to be signed in 1993.
In January 2000, the west end toll plaza of Alligator Alley was dedicated to the memory of Edward J. Beck, a toll taker who was murdered while on the job on January 30, 1974. On January 28, 2002, the Florida Department of Transportation began a transition of interchange numbers from sequential exits to mileage-based exits.
In October 2009, the Florida Department of Transportation (FDOT) began a relocation project for the northbound ramp of exit 275, which includes a connecting ramp with I-275. This project was designed prevent weaving in the vicinity of I-275 and SR 56, a hazard that has occurred since the exit 275 and SR 56 were built across I-75 in 2003. Completion was expected to take place in early 2012.
Plans are under way to redesign the interchanges with the north end of Florida's Turnpike (Exit 328) and SR 44 (Exit 329), connecting them with collective-distributor roads, and eliminating left-hand access to Florida's Turnpike from the main southbound lane. This is a joint effort between the Florida's Turnpike Enterprise and Florida Department of Transportation and is planned to occur in 2016.
FDOT is implementing express lanes along 28 miles (45 km) of the I-75 and SR 826 (Palmetto Expressway) corridors, from just south of the SR 836 (Dolphin Expressway), in Miami-Dade County, to I-595 in Broward County. This project will complete another section of the South Florida managed lanes network for all motorists and will improve mobility, relieve congestion, provide additional travel options and accommodate future growth in the area. The 75 Express Lanes project extends 15 miles (24 km) along I-75 from Northwest 170 Street, in Miami-Dade County, to I-595, in Broward County. Work will be completed in four segments to minimize affects to the public. Construction began early 2014 and is scheduled to be completed by mid-2019. The total project is estimated to cost $481 million.

Along I-75 are 9 pairs of rest areas along the length of the freeway. In addition, there are separate facilities for each direction of I-75 in Hamilton and Suwannee counties, southbound and northbound, respectively, and a welcome center south of the state line. Exits 131 and 161 each have a single facility accessible from both travel directions on I-75, as well as the intersecting highway. Each rest area has rest rooms, vending machines, picnic tables, dog walk areas, and nighttime security. The welcome center also has travel information and free orange juice.
Motorist-aid call boxes, which were installed in the early 1970s on both outside shoulders of the road every mile (1.6 km) to allow drivers to indicate the need for gasoline, repair (tire or engine), or emergency services (police, ambulance, or firefighters), were removed in late 2013.
Intelligent Transportation Systems, which include surveillance cameras and electronic message signs, have been installed along I-75 throughout Florida in recent years. ITS systems are currently operating from the south end in Miami to the Tampa Bay metro area. 
The Everglades Radio Network is a network of travelers information stations serving Alligator Alley in the Everglades region and based at Florida Gulf Coast University in Ft. Myers. It consists of two low power FM radio stations.
