I remembered seeing zone A masterplan n if I am not mistaken it includes some areas along tebrau highway such as taman melody, taman century n taman sentosa. Particularly the high rise developments along jalan dato abdullah tahir n wadihana. Also jalan yahya awal, jalan kolam ayer, etc shd be part of zone A since u need to drive past these areas to reach danga bay.
confirmed it is the not the case, most ppl have a lot of misconceptions towards iskandar project, such as they always called "nusajaya" as "iskandar". Same went to zone A. If you read the official info. It definitely only refers to JBCC (including Danga Bay)
flagship zones refer to the focused areas that consisted of major developments that are driven and supported by central gahment, state johor. areas like tebrau, permas etc there are just normal developers driven projects which all the while existed in JB. This is one of the major reason that there is no major development announced for the area.
danga bay does not need to drive pass these areas as danga bay is only located next to JBCC. it is along the coastal.
looking at the official info, you can see that flagship A is clearly labelled.
