Part of Karakoram Highway was submerged due to this landslide. On 14 September 2015, the Prime Minister of Pakistan, Mian Nawaz Sharif, performed the inauguration of the realigned 24 km (15 mi) patch of KKH containing five tunnels at Attabad Barrier Lake. The five tunnels are known as the Pakistan-China Friendship Tunnels, and are collectively seven kilometres (4.3 mi) long. They are part of the 24 km (15 mi) long portion of the Karakoram Highway (KKH) which was damaged in 2010 due to land sliding at Attabad. The realignment project is a construction masterpiece completed at the cost of $275 million. The realignment restored the road link between Pakistan and China and it is expected that significant amount of trade will be conducted between China and Pakistan using it. The KKH is also a part of the China Pakistan Economic Corridor and is expected to significantly increase economic integration between those two nations
