Alligator Alley (also known as Everglades Parkway) is a section of Interstate 75 (State Road 93) and State Road 84 extending from Naples on the west coast of Florida to Weston on the east. First opened in 1969, most of the highway traverses the Everglades.
The name was given by the American Automobile Association during planning; 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.
Route description 
Alligator Alley itself is currently the portion of Interstate 75 that carries the hidden designation of Florida State Road 84. SR 84 is picked up at the east point at Exit 22, after straddling I-595 and I-75 as a frontage road for about 14.4 miles (23.2 km) prior. It then continues across rural Broward and Collier Counties, passing the lands of the Seminole Tribe of Florida, until letting go of SR 84 at Exit 101 in Naples.
Currently, automobile drivers pay a $3.00 toll ($2.75 for SunPass users) both eastbound and westbound, and it is one of only three tolled sections of Interstate 75. There are two exits along the roadway, neither of which charges a toll to enter or exit the highway.
It 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). After it was determined that I-75 was using this route for the Tampa-Miami extension instead of the Tamiami Trail in 1973, it was widened to four lanes 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, as well as reducing the danger of the highway, which was notorious for high-speed accidents.
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, January 30, 1974.
