I am afraid latest news is that the project has been abandoned.
Reason being it was a project of former govt. so no one wants it to go ahead, neither PPP nor PMLN. They are even starting to give back(sell) the land purchased for this project so no hope at all.
Lets hope Gilani will do something about Multan motorway (his home city), but considering how development budget has been cut in every budget, that too looks unlikely beyond paper work.
