In the morning I attempted the route via Loke Yew bottleneck. It was clear but the flyover is crawling prior to the adjoining of Jln Tun Razak, smart tunnel, and the KL-Putrajaya exit. In other words, saved Ringgit Malaysia 2 but lost slightly more than half an hour.
Whereas en route home from work I was measuring an alternative route of RM1.30 toll at 15.9km +-0.1km vs the normal route of RM1.60 at 16.6km +-0.1km. Conclusion: convert alternative route as primary route.
