If I want to get to Bt. Merah I would plop myself on a Sv. 56
from interchange and x-fer Sv. 153 at TPY. An alternative is for
Sv. 153 to ply along AMK Ave 1 / Boundary Rd such that it goes
through Bishan, the amended route would be something like this
:
Original route to Boundary Rd
Boundary Rd
AMK Ave 1
Bishan Rd
Braddell Rd
Lor 6 TPY
Back to original route.
Another alternative is for Sv. 153 to ply Bishan Int in BOTH
directions, ie, via St 14, St 13, Bishan Int, St 11 and on to
Bishan Rd.
