Carol - The jetways attached to the terminal on the 2nd floor. We went through these doors and turned right and down the jetway. I suspect that when the 1st floor arrival area is completed you will come into the terminal behind the doors in this picture and go down an escalator to arrivals on the first floor without entering the 2nd floor departure area. It would be chaos to have arrivals enter the departing floor and go against the flow of traffic to get outside to get to the temporary arrival building. Hope this helps.
