Traffics always been bad in that area. Now that they have decided to let in more people, they are building some new roads.
They've already notified land owners in Bishan, Marymount Convent, Lee Ah Mooi old folks home, etc that they are going to take their land for some kind of road extension program.
However since the traffic is already so bad & they plan to let in more people, it will still be bad even if they build more roads
