Pier B will be rebuilt and integrated to T3. Pier C most likely retained and linked to T2. Pier 3 and 4 unlikely ever build, certainly not in next few years! Old T1 building likely to be become mothballed until demolition in 50 years time!!
Are you stating just your assumption(s) here or will MAG officially be announcing such projects in the near future?
We need a definite answer ref the future of the T1 building and both piers ASAP!
