AOA Brother Ahsan from fsd to isd you may opt moterway or old shekhupura >Gujranwala wala rout or shekhupura >shahdara>Gujranwala >Islamabad rout
But from isd heading to onward two routes 1-isd > Hassan Abdal >abbotabad >mansehra>balakot>naran
2-isd> nathia gali >abbotabad >mansehra
3-isd >murree > muzaferabad >gari habibullah > balakot>neran , I think today’s 3rd one is best rout to avoid traffic jam of abbotabad mansehra area and also avoid extreme hot weather
