It has been confirmed that work on the second multistory inside the CTA should start next year with part of the mid term also getting an upper floor via some sort of mezzanine floor arrangement.
We will have to see if the replacement drop off zone will be inside the multistory with drop off lanes running through the middle of the ground floor or external to it. Also how the airport intends to get passengers over the ring road as the existing footbridge is just not wide enough. I am thinking it will have to be via a slope arrangement due to passenger volumes.
