go to lahore on motor way. where m-way finishes head towards multan on gt road. gt road pe okara sahiwal etc ain gay. then khanewal. from there i think you have 2 options one is to bypass multan and the other is go thru it. phir i dont know you can always ask ppl which way to follow.
i have never travelled thru m-way to faisalabad maybe deres a better way from faisalabad towards RYK.
