Kashmir highway and sector i-14,15 and 16

Will sectors i-14,15,16 be linked with the kashmir highway when extened till the airport?

Seems unlikely! Kindly take a look at the following news report from a few days ago:

also the following thread

New plans include not having link road. So will kh only get widened and direct route to airport. Second route maybe benefit those above sectors.

No, Plan cancelled already.
