(14.2miles), Treasure Island in the middle (3.5 miles) and Long Key at the south end (4.1miles).
Treasure Island has undergone a total of 11 renourishments to date, and was the first segment constructed.
Long Key is the second oldest and has been renourished seven times over the course of its 37-year life, and finally Sand Key, originally constructed in 1993. It is the largest of the segments and is set to expire in 2043, undergoing three renourishments to date.
