Actually you can consider since the DASH highway will connect you to Damansara.
For example places like 1utama or uptown damansara that require almost 1 hour travel time will be cut down at least half I think

I think from EG to DASH still oklah.
The problem now is the chokepoint at exit Toll Bukit Jelutong and also after the Tol Damansara heading Sprint there.

DASH should cut down a lot of all this chokepoint hopefully.

But this only applies if you ok with travelling all the way to Penchala before heading to KL instead of using Sprint or you're working around PJ/Damansara Area

Had a unit in Hillpark unfortunately.
My wife used to work in Puncak Alam and I'm working in TTDI

That's why I'm quite familiar with the journey between the places

Not sure about DASH
but before DASH, the old road is quite jam packed at times.

But from puncak alam to NKVE still OK. The only places I don't like is after the Damansara Toll heading Sprint Highway
The bottleneck 2 lanes is there and that's why I fully support the PJD link
