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. At 472 miles (760 km), I-75 is the longest interstate in Florida. Interstate 75 is unsigned State Road 93 for most of its length in Florida (the exception is in the Tampa Bay area, where State Road 93 follows I-275, while State Road 93A travels with I-75 in the latter's bypass of the area).

Route description

The south end of I-75 near Miami

Interstate 75 begins its northward journey at SR 826 (Palmetto Expressway) near Miami.^[1] 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 SR 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 Highway standards. Part of Alligator Alley runs through Collier County, and the Big Cypress National Preserve. 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).

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 Bonita Springs, 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) Interstate 275 splits from Interstate 75 to serve St. Petersburg and Pinellas County via the Sunshine Skyway Bridge and Tampa via the Howard Frankland Bridge. 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 (SR 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. Within the Tampa Bay Metropolitan Area, many interchanges are far more complex than mere diamond, cloverleaf, or even SPUI interchanges. Besides the massive catherine wheel interchange with Interstate 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 new flyover ramp is currently being 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)), 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 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.

The Cross Florida Greenway bridge over Interstate 75.

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 beneath the Cross Florida Greenway, which contains a land bridge built across the highway in 2001 between Exits 341 and 350,^[2] before entering the City of Ocala, and passing by the cities of Gainesville and Lake City and crosses Interstate 10 at an interchange before leaving the state of Florida at the Georgia border near Valdosta.

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.

History

This section requires expansion.

Originally, I-75 was to be built to Tampa, terminating at I-4's current western terminus. After I-75's route was extended to connect into the Miami area, a Tampa Bay bypass was built east, signed as I-75E, with the original route, now extending to St. Petersburg and becoming a loop, signed as I-75W. After the AASHTO phased out route suffixes on Interstates, I-75E became I-75, and I-75W was renamed I-275.

From Naples, Interstate 75 was originally intended to run along the current route of US 41/Tamiami Trail, and connecting to I-95 along the current route of State Road 836/Dolphin Expressway. Due to environmental concerns of the Tamiami Trail and wanting to upgrade the then dangerous Alligator Alley, the latter was upgraded to interstate standards. After rerouting I-75 south of what would be I-595, I-75 was to terminate at I-95 in North Miami, but due to local opposition, I-75 was not built past its current terminus of the Palmetto Expressway.

Future improvements

Florida Department of Transportation is currently proposing a relocation project for the northbound ramp of Exit 275, which includes a connecting ramp with Interstate 275. This project will 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.^[5]

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.^[6]
