China Opens World’s Longest Highway Tunnel Through Xinjiang’s Tianshan Mountains
China has opened the world’s longest highway tunnel in Xinjiang, a 22.13 km engineering marvel cutting through the Tianshan Mountains. The Tianshan Victory Tunnel enhances regional connectivity and showcases China’s advanced infrastructure and tunneling expertise.
The tunnel, officially named the Tianshan Victory Tunnel, cuts through the rugged Tianshan mountain range, an area long known for its complex geology and harsh terrain. Engineers involved in the project confirmed that the construction required tunneling through as many as 16 geo-fracture zones, a challenge that placed the project among the most technically demanding highway works undertaken anywhere in the world.
According to experts, the successful completion of the tunnel reflects China’s advanced engineering capabilities and its ability to execute large-scale infrastructure projects under extreme geological conditions. The project is being widely described as a world-class engineering achievement, underscoring the country’s growing expertise in tunnel construction and mega infrastructure planning.
With the tunnel now operational, travel across Xinjiang is expected to become faster and safer, reducing travel time through mountainous terrain that previously posed major logistical hurdles. Authorities anticipate that the improved route will enhance regional mobility, support economic activity, and strengthen internal connectivity across the vast western region.
Beyond its immediate transportation benefits, the opening of the Tianshan Victory Tunnel stands as a powerful symbol of China’s technological progress and long-term infrastructure vision. As traffic begins to flow through the tunnel, the project is set to play a lasting role in shaping mobility and development across Xinjiang, while reinforcing China’s position at the forefront of global engineering innovation.
