Back to FL exit lists.
Airport Blvd is a south extension of FL 436 (Semoran Blvd) thru the airport. The parking is in the wide median, and light rail-type shuttles go over Airport Blvd to the terminals. In the 1990s the south entrance was made to connect TOLL 417 and CR 527A (Boggy Creek Rd) to the airport. This is a super 2 with a couple temporary intersections for construction of the new south terminal.

Thanks to the Orlando Intl Airport control tower for having a map of the planned expansion on the wall when I went there.
