Well, have u heard of North Shore / Coast line as well? Do you
that Punggol MRT station has another cutbox tunnel for provision in
this MRT line.
Maybe we can know when the CCL Stage 4 opens. (Seriously,
Between Orchard, Holland Village and Ulu Pandan area needs a MRT
line that might jolly well connect to Bukit Batok)
Lol, there are box tunnels under Punggol MRT station and LRT
station.
Possibly that it could connect to Changi Airport, Changi
Village, Pasir Ris, <Broadwalk/Park Connector between Punggol
and Pasir Ris), Punggol, Selatar, Lentor, Woodlands
