, in the original plan for 41,000 miles of interstate highways. However, beginning in the 1960s, there was a huge growth in the population of southwestern Florida (Sarasota, Ft.

At first, Florida state legislators proposed a toll in the new highway, but by 1968, it was decided that the Federal Government would pay 90% towards the extension of I-75 to southwestern and southeastern Florida. This included subsuming a privately-owned toll highway from Naples to the Fort Lauderdale area, the Alligator Alley
