Upgrades to the 487-kilometer long section between Burhan and Raikot of the Karakoram Highway are officially referred to in Pakistan as the Karakoram Highway Phase 2 project. At the southern end of the N-35, works are already underway to construct a 59-kilometer-long, 4-lane controlled-access highway between Burhan and Havelian which upon completion will be officially referred to as the E-35 expressway.[89] North of Havelian, the next 66 kilometres of road will be upgraded to a 4-lane dual carriageway between Havelian and Shinkiari.[90] Groundbreaking on this portion commenced in April 2016.[91]
