What if LTA introduces a route from CCK to Sengkang?
Just saying, it's not quite possible by history of LTA
routes.
The reason why LTA now build more bus interchanges at North East
Line / Tampines is because so that they can undo 97, 106 and
111, re-instate withdrawn NEL services.
97 Jurong East - Tampines Concourse
106 Bukit Batok - Punggol
111 Ghim Moh - Farrer Park (Loop)
373 Compassvale - Fernvale Road (Loop)
501 Compassvale - Shenton Way via Outram Road
