Oh yes, perennial, if I can recall correctly...
Back in mid-70s the Cheras jam was already there, from All St Church to Tmn Pertama roundabout then to Midah/Billion roundabout..
In the early 80s, the jam extended to Connaught and even further.
There came the ramp-road from Tmn Mutiara Barat to Midah. Toll paid but still jam all the way to Midah. Toll abolished.
Then there came East-West Link. Toll paid. Jam all the way to PJ. Toll abolished.
MRR2 built. Traffic not much improved. Jam from Pandan to Midah/Billion roundabout, until today
The jam was getting worse until Kajang.
In 1999, Grand Saga Highway was in operation. You know the story since.
No need to decsribe about the jam at Cheras Sentral.
There is SUKE proposal, but some resident tak suka.
Of all the highways built at Cheras, it did not help in mid-to-long term.
Jam is still there as you have witnessed today.
So, will MRT help? You hve the answer in your mind already.....
KL and PJ is commercial business centre and the federal road is spacious then jln loke yew.
yet there are lrt connected from ldp to federal and to klcc.
if you stay in cheras and the working opportunity is there and yet the public transport not fully covered, you will definitely need buy a car and drive along the way, that where the jam come from.
MRT is definitely can help to ease up the way to kl, but not the way to PJ so far.
