This is the 1st post about route you can use to avoid tolls. At this moment, mostly I be posting route to Cyberjaya where I work and will post more for any route that I know.
Still not confirm about this route but here it is.
From Puchong > Bukit Puchong > Putra Perdana > Bandar Nusaputra EXIT to Interchange Lingkaran Putrajaya and Selangor Science Park 2.
Go into Selangor Science Park 2 and you will exit via MMU.
Distance: Unknown
Cost: RM2.20 (Kesas) + RM1.60 (Puchong)
This route is more suitable people stay near Bukit Puchong
