Dunno why, why Singapore no make underground bus
interchanges/terminals? Woodlands and CGA are good examples they
have made, why not continue? The interchange can connect with the
basement of the shopping mall, if that's what the PTO
wants.
Underground interchanges allows more spaces for bus. If only
Serangoon Interchange was built that way, then 81, 82 would be
saved from rezoning. I strongly recommend Marina Centre Terminal to
be built underground. That way LTA no need get paralysed finding
open spaces in the CBD to build a terminal, and will also stop the
case where buses park at the Singapore Flyer there. I have seen
cases where the road was clogged up and buses get severely late
just to wait for the BCs who drive the buses in front to start
THEIR trip.
82 should merge with 107 and rename 102.
