its the developement of Sembawang, part Woodlands, Punggol,
Sengkang and part Hougang that leads to the traffic jams on CTE
today.
cos the other alternatives are Upper Serangoon (for NE side) and
Thomson, and these are worse roads with twists and turns
those commuting from eastern or western sides have 2 4-lanes
expressways to serve them.
CTE only 3 lanes for most of the way
