One day it may be materialised ......maybe not in Punggol but in other locations either in Singapore or nearby islands. Tell you a true story.............I was told in year 1965/66 session in Singapore Polytechnic, a group of students in Architectural Draughtmanship Dept., together with some Architectural lecturers are doing a similar dream for a class project. The topic was......." a dream Singapore Skyline along Shenton Way ".
You know what happen ? They came up with some fantastic idea of filling up the sea alongside Shenton Way, with housing, reservoir and an overhead expressway with MRT running from reclaimed land, right up to Eastcoast.
Today you have Marina Bay and Sheare's Bridge minus trains. It happens ....ya ?
So not to worry..........ideas will be taken up eventually..........Best wishes.
