I guess lodhran khanewal expressway would b better cux the road is almost fully built now, around 15 odd km bumpy patch remaining. It has relatively lesser traffic n shorter distance. So u can take that. Besides, it is rumored that lahore-abdul hakim section of motorway is going to open very soon, 15th or 19th of this month. Lets hope it gets operational n then u can enjoy motorway from lhe to multan n then follow n5 to destination
