Interstate 75 is one of the interstate highways in the midwest and southeastern United States, and the primary north-south interstate highway along the west coast and southern end of the state of Florida.

Bold cites are AASHTO control cities.[1]

Interstate 75 begins its northward journey at FL 826 (Palmetto Expressway) near Miami in Hialeah. It is also the national southern terminus of the interstate highway that runs to the Canadian border at Sault Ste. Marie, Michigan.

Leaving Hialeah, Interstate 75 crosses into Broward County and continues through the Miami/Ft. Lauderdale suburbs of Pembroke Pines, Weston, Miramar, Davie, and Southwest Ranches. At the junction of FL 869 (Sawgrass Expressway) and Interstate 595, Interstate 75 (while maintaining its north/south status) enters an east/west 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 standards.

Once near Naples at Collier County Road 951 (Exit 101), Interstate 75 once again assumes its north/south trajectory. Interstate 75 runs parallel with the southwest coast of Florida and passes near Fort Myers, Punta Gorda, Port Charlotte, Sarasota and Bradenton before reaching the Tampa Bay area metropolis consisting of Tampa and St. Petersburg.

In Ellenton, (a small community northeast of Bradenton) a branch of Interstate 75 splits to serve St. Petersburg and Pinellas County via the Sunshine Skyway Bridge and Tampa via the Howard Frankland Bridge; this branch is called Interstate 275. Meanwhile, Interstate 75 parallels the eastern shore of Tampa Bay as it passes by the communities of Brandon, Temple Terrace and New Tampa. Tampa is accessed from Interstate 75 by way of either the Lee Roy Selmon Crosstown Expressway (FL 618) or Interstate 4. Interstate 75 as it passes east of Tampa is considered the bypass route while Interstate 275 serves the downtowns of Tampa and St. Petersburg.

At the Hillsborough-Pasco county line (south of FL 56 (Exit 275)), Interstate 275 rejoins Interstate 75 (Exit 274 southbound Interstate 75 only) and Interstate 75 slightly changes into a northeast-southwest trajectory as it passes through Pasco, Hernando and Sumter Counties on its way to the junction with the Florida Turnpike.

After the Florida Turnpike (accessible from southbound Interstate 75 only), Interstate 75 changes into a general northwest-southeast trajectory and remains so all the way to the Georgia state line and beyond. Interstate 75 passes by the cities of Ocala, Gainesville and Lake City and crosses Interstate 10 at an interchange before leaving the state of Florida at the Georgia border near Valdosta.

The distance from Hialeah at FL 826 to the Georgia border is 472 miles, which makes Interstate 75 the longest of Florida's four principal interstate highways.

Interstate 75 runs closest to U.S. Route 41 except between Tampa and High Springs. It runs closer to U.S. Route 301 between Ellenton and Temple Terrace, and again from Dade City to Sparr. From Belleview to Lake City it runs closest to U.S. Route 441.

In Collier County, Interstate 75 runs through the Big Cypress National Preserve, while in Pasco, Hernando, and Sumter Counties, it runs through parts of the Withlacoochee State Forest. Trails that cross I-75 include the Withlacoochee State Trail and Cross Florida Greenway, which contains a land bridge built across Interstate 75 in 2001 between Exits 341 and 350^[2].

State Roads 93 & 93A

Like any other Florida interstate, there is an unsigned state road designation associated with Interstate 75. For most of its length in Florida, Interstate 75 is unsigned State Road 93. The lone exception is in the Tampa-St. Petersburg area, where it is unsigned State Road 93A. This is because SR 93 was designated along the original I-75 routing. When the Interstates were renumbered, the state route designations were not changed to match.

History

Originally, I-75 was to be built through Tampa and St. Petersburg, while the current I-75 was to be called I-75E. Because of Interstate restrictions dealing with suffixes to routes, I-75 was rerouted along I-75E, and the original I-75 was renamed I-275.

Auxiliary routes

• Interstate 275 goes into downtown Tampa, across the Howard Frankland Bridge into St. Petersburg, then south across the Sunshine Skyway Bridge, reconnecting with I-75 in Manatee County, Florida.

• I-175 and I-375 are very brief Interstates that go east into downtown St. Petersburg.

Lane Configurations

• Between Georgia line and Florida's Turnpike (Exit 329) (3 lanes each way)
• Between Florida's Turnpike and State Road 582 (Fowler Avenue) (Exit 265) (2 lanes each way, but gradually being widened to 3 lanes each way)
• Between State Road 582 (Fowler Avenue) and State Road 681 (Exit 200) near Nokomis (3 lanes each way except through Riverview and part of Brandon where it is up to 5 lanes each way)
• Between State Road 681 and Harborview Road (Exit 167) (2 lanes each way)
• Between Harborview Road and US 17 (Exit 164) (3 lanes each way)

Notes

The Alligator Alley section west of Fort Lauderdale, Florida is due east/west and is one of only two sections of I-75 that are tolled (the other is the Mackinac Bridge). Interstate 75 was originally intended to run further south of State Road 84/Alligator Alley, along the current route of US 41/Tamiami Trail, and directly into downtown Miami along the current route of Florida State Road 836/Dolphin Expressway. The eastern terminus of Alligator Alley, the southern terminus of Sawgrass Expressway, and the western terminus of Interstate 595 are in the same stack interchange.

Plans are currently 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.
