if you want to go to FSD the best route is take M2 by pindi bhattian
i have tried couple of months back the below routes
Take M3 exit Nankana Sahib interchange, take Manawala road to Shiekhpura-FSD Road the distance is short comparing to M2 but it take ur extra 15-20 min depend on traffic
also i have checked M3 exit Jaranwala Interchange, couple of months back road new constructed till chalii morr the route is fine but again it wasting your time
if you want to go to FSD City as per my opinion the best route in Pindi Bhattian
