Extend Terminal A
Terminal A will be extended to the south to provide two additional aircraft
gates.
Construct Terminal C
A new terminal – Terminal C – will be required to meet 2030 demand.
The proposed terminal layout locates Terminal C landside parallel to the
existing roadway and with a six gate concourse pier which extends parallel
to the concourse piers of Terminals A and B. All three terminals will be
connected by a corridor which will allow passengers to circulate through
the terminal complex, both pre- and post-security, therefore creating a
unified terminal complex.
Additional analysis was done to ensure that the recommended terminal
layout for 2030 could be expanded to meet 2050 demand on the existing
terminal site.
