The Khunjerab Pass is the highest paved international border crossing in the world and the highest point on the Karakoram Highway. The long, relatively flat pass is snow-covered during the winter season and as a consequence is generally closed for heavy vehicles from November 30 to May 1 and for all vehicles from December 30 to April 1. No additional upgrade is proposed for the Khunjerab pass section of KKH in the current reconstruction phase.
