Parking Structures 1, 3 and 4 were designed to serve short-term parking needs of the airport. Structures 3 and 4 are connected at the third level to provide a total capacity of 2200 spaces. Structure 3 provides a public-use heliport on the top level. A tour bus parking area is incorporated in the grade-level design between the two facilities. Pedestrian bridges connect the structures to the three adjacent buildings.
