No my friend its different from existing super highway or N5 . But you are right all the mapping and most of the terrain study has already been completed and its a matter of funds and tenders allocations to kick start the work .
This motorway will be built in phases as shown and will pass very near to sindh-balochitsan border and also from some remote undevelopded areas of south punjab resulting in better and fast development of many impoverished areas .
But I would agree with @
darkinsky there are many more important issues than this like internal security and gwadar links but if Pakistan can kick start all of them together without hampering other projects I guess its good for our development as this motorway will cut Isl to khi time from current 21 hours to 12-13 hours . I mean non - stop driving on personal cars .
As shown M-8 will be connected to Gwadar as well and also Gwadar-china link road will be connected to M-8 . It was wrong of PMLn to paint this project as Lahore-Khi motorway as its gonna be attached to current M2 right in centre and can easily be called as a karachi-Islamabad motorway to give this news national colors . Infact it will be started from M-4 segment connecting faislabad with multan .
