No vehicles close to the Tinminal in two years time? Sounds plausible and a nightmare for ACDL who inherited a central area with only a single access/exit point!
Mind you, Parkway was to be one of the primary 'check in' zones and a tram like contraption was to be constructed linking the two (thus the third lane not used under the taxiway). This was 'financially' design engineered out of the Parkway project which in hindsight was encouraging the use of public transport, so was 'green' in concept well ahead of its time!
