Besides that, there is no expressway too to link NW to NE. For
example, if one wants to go from LCK to Punggol, he has to drive
one big round if he wants to go via expressway.
Anyway, I just feel that most of the highest demand routes that
SMRT has like 190 are previously from SBST. Like for 190, it is
direct, straight towards from CCK to city. 180 too, takes a direct
route via Bt Batok Rd to the western areas from Bt Panjang.
Routes like 88 goes a big round at the Hougang area when it is
going from Sengkang to AMK.
