Nine years of construction to solve the "roadblock" of the entire line. The Lixiang Railway will be completed and opened to traffic within this year, affecting the tunnel and railway
CCTV News: The 9523 meter long Haba Snow Mountain Tunnel is located in the Diqing Tibetan Autonomous Prefecture of Yunnan Province, in the northwest longitudinal valley of the Hengduan Mountains on the Qinghai Tibet Plateau. Due to the long-term activity of multiple fault zones, problems such as landslides, karst, and large deformation of soft rocks are extremely prominent. Our reporter recorded the process of the builders overcoming difficulties through camera.
Since the construction of the Haba Snow Mountain Tunnel, construction workers have been struggling to excavate in various unexpected situations.

This is a landslide that occurred in April 2021, with broken rocks gushing out like water from the mountain and the sound of steel bars breaking at the scene. The landslide lasted for about 20 hours, with a cumulative amount of over 1000 cubic meters.
When construction began, the Haba Snow Mountain Tunnel had three working faces, but due to significant deformation, the maximum number of working faces increased to 22. At the same time, railway, design, and construction units have organized 8 expert seminars, with 29 well-known experts conducting multiple discussions and dynamically adjusting disposal plans.

CCTV reporter Liu Wenjie: It is now May 10th, and the workers are carrying out the dismantling and replacement of the tunnel support. The entire dismantling and replacement work is now only the last 30 meters, and it can be said that the construction of the entire tunnel has also entered the sprint stage.
With the completion of the Haba Snow Mountain Tunnel, the construction of all 20 tunnels on the Lijiang Shangri La section of the Yunnan Tibet Railway has been completed, and it will enter the long track laying stage, marking the countdown to the opening of the entire line.

According to the plan, the Lixiang Railway will be completed and opened to traffic within this year. Diqing Tibetan Autonomous Prefecture in Yunnan Province will end its history of no railway access, greatly filling the gaps in railway network and transportation services in the northwest region of Yunnan.
