Very interesting you bring this up. The plans for the new existing Southwest terminal and a north terminal have nothing to do with one and other. There we're plans for a north terminal, which would have occupied the recycling facilities land. The plan for a north terminal is over ten years old and there were political issues between Islip and Brookhaven town that doomed the project. The train station sits on both Islip and Brookhaven town land and there were issues concerning access roads, people movers from the station to the terminal, parking at the train station (which is an issue on its own), and in the end how revenue would be shared between the two townships. Islip felt revenue was there's to keep but Brookhaven felt it should be shared if passengers were going to access the airport from Brookhaven land, i.e. the Ronkonkoma train station.
It truly was sin the project failed. A combination of the nations largest commuter rail system and a well equipped regional airport only an hour from NYC would have been a huge economic boom for region. Even now people from NYC travel via the LIRR to ISP
to fly Southwest. I was lucky enough to see plans for the north terminal and the coolest feature was the people movers from the station to the airport. The system was similar to the people movers found at TPA
, and LAS
As is stands now the new terminal, the plans for old terminal, and the newer part of the old terminal should make ISP
a world-class regional airport. There are no plans for a parking garage, however construction is underway for a 2000 space parking lot that is being built to the right of the new terminal.
