christie/metro >> The traffic there just in front of the TMJ and Bukit Panjang junction is very bad during peak hours. Also, that same road leading up towards Woodlands is often used by goods vehicles going to Malaysia. That time during the Mas Selamat escape, many of those trucks and long vehicles clogged up that road, from Woodlands checkpoint, all the way down to the road just in front of Senja Green.
Also, the other stated junction is quite badly designed as of now (towards Bukit Panjang from Bukit Timah). It is a 3 lane road leading to a 4 lane junction - Extreme right lane is a right turn lane, the next lane is a straight/right turn, followed by a straight lane, then the left most is a bus lane.
During peak hours, the left lane is empty coz no one dare to drive on bus lane. The 2 right lanes are clogged with vehicles trying to turn right into Dairy Farm. Those traveling straight towards BP are blocked by those 2 lanes as it is 3 lanes extending to 4 lanes. I have ever been stuck in the jam for more than 20 mins (for a 2km stretch) waiting for the traffic lights to turn in favour of the right turning vehicles so that they can clear the junction for me to go straight...
Hopefully the new MRT line will ease some traffic... But both the MRT n flyover will only be ready in 2015. From 2012-2015, with all the construction going on, we will definitely need to bear with the jams.
