Thanks to another poster who already addressed your question

Old Subang Airport road jammed all the way, as people are cutting in to NKVE

On the other hand, driving to federal from Old Subang Airport road is also the same

The tunnels connecting Ara Damansara to PJ is also jammed af, to and fro from PJ

And sometimes the tunnel doesn’t even open

I’ve stayed in Ara Damansara for a brief period of time and my office was only at Sunway at that time

And I can honestly tell you that I was so happy to move out from there
