No need cause Marina South got plan for bus terminal.From
Shenton Way can loop there already.
Rumah Tinggi no need le,63 can start from Eunos-Bt Merah and
introduce a short trunk from Bt Merah loop at Rumah Tinggi lor
Seriously Marsiling need a Terminal.
Kranji also good for 170X.
If 63 is extended to Bukit Merah, no need for trunk service, 63
can do the job itself.
If Kranji gets an interchange, will take off some load from
Woodlands Interchange.
