Alligator Alley is a nickname for that section of
Interstate 75 that runs from
Naples on the west coast of
Florida to near
Fort Lauderdale on the east. Much of the highway traverses the
Everglades. It was originally built as a two-lane highway connecting the two coasts of Florida, and was later connected to Interstate 75 as an east-west continuation of the
highway, which otherwise ran north and south. Between
1986 and
1992, it was widened to four lanes.
