Not too good route-wise, because it would be somewhat
duplicative of 188/985.
If an extension of 308 is desired, it would be better to route
it through the BB West new area (and possibly to Jurong East)
because that place genuinely needs inter-town services.
188/985 dun serve Keat Hong (CCK N8). My suggested merger of
308/947 will help provide those living in that area with more
options. The map says it all.
944 being run by SMRT makes it better off as part of an
intertown route originating from CCK incorporating the current 308.
Not sure if there is any right turn from BBT West Ave 5 new section
to BBT Rd though.
