The longest tunnel of China-built Karakoram Highway relocation project was successfully dug through on Thursday. The Logro-B tunnel, a 1,403-meter section of the Karakoram Highway linking Pakistan with China, is designed in compliance with Chinese tunnel design standards. The realignment project of the existing Karakoram Highway is undertaken by the China Civil Engineering Construction Corporation (CCECC). This project includes seven tunnels and three bridges in the mountainous area of northern Pakistan, where the natural conditions are harsh, due to frequent occurrence of disasters such as earthquakes and mudslides. In the next phase, the project team will advance the remaining bridge and tunnel works to ensure the project's high-standard and high-quality completion. The Karakoram Highway, located in Pakistan's northern Gilgit-Baltistan region, is also known as the China-Pakistan Friendship Highway. It is the only land route linking Pakistan with China.
