Both...

I hear that area always jam in morning. But if you like this area & afford it do you consider? Depend what you needed.

ya, I think jam before 7am is the worst, normally I went out around 8am via sg long exit from deep inside of mahkota cheras, only took 15min-20min. thats why I think the jam before 7am is because a lot parent fetch their kids to school.

Not sure the time between 7am - 8am..let other to share. 
After 8am, very sure, but my info is until the exit of cheras-kajang highway, because I went to cyberjaya in different direction. Even not jam from sg long after 8am, but the jam maybe worse in other place such as taman connaught or near to leisure mall.

You move to which part of sg long?

TP can take Silk highway.

i'm one of them  
the traffic ease after 8am, but still moving slow until 9am.
these few week i try 9.30am out from sg long, not jam at all
if the BMC side traffic lights @ grand saga exit broke down or someone turn it off, there will be no jam at all
not any better from TP ler.....

silk highway --> jam at the mines
silk highway --->jln sg long Q from taman rakan2 --> grand saga ---> kl, jam start before batu 9 tol
silk highway --->jln sg long Q from taman rakan2---> grand saga --->silk HW --> kajang/ bangi, jam start @ sungai chua

only silk highway ---> semenyih side guaranty not jam

I used to love Sg. Long but now I love BMC more. Sg. Long is boring...

this one have to "slow slow wait"
early this week, the newspaper reported that SILK and Government had refused the suggestion

Agreed, since the road already built half way, only few metres away can link to SILK h/way dy.

The road behind Bukit Sg Long.
