Is this the one you are talking about?
https://en.wikipedia.org/wiki/Reconstruction_of_the_Karakoram_Highway
I see your map is aligning with the one present here.
National highway N-35.
From what is written in wikipedia, it seems Raikot to
Khunjerab Pass and Khunjerab Pass itself are still part of this new reconstructed highway. The wikipedia states that there are no plans to upgrade Khunjerab Pass itself.
But then wikipedia is often out of date. Do you have some more recent articles that has plans of upgrading the Pass itself?
Please look at my post above.
And feel free to post articles or other news about upgrade to Khunjareb Pass. We can then update wikipedia as well.
I don't have local news from Pakistan. If you have local Pakistan based news covering CPEC in detail with regard to connectivity and its year round operation, feel free to post.
