Going to Seremban from Kepong is the one part I hate. I took me an average of about half an hour (I think, or longer) to reach the Sungei Besi Toll. And so, today, I noticed the new DUKE highway (Duta Ulu Kelang Expressway) entry and I decided to take a risk (to see where I ended up). Not much traffic though as the will not be charging for at least another month. But if I am not mistaken, the route from Kepong to Seremban (via Duta) has no toll gates. Heh heh.
Woowee! There's not much cars on the road and yes, you could really pie in the middle of the road and not get hit by a car.
And this is the exit I must go, it comes out somewhere near the Jalan Duta NKVE entry, so you must keep looking out for the "Seremban" signs. I think I save quite a bit of time on this.
