As Xinjiang’s rugged Tian Shan Mountains yield to technology, a record-breaking tunnel reshapes travel, trade, and regional connectivity

Introduction

In a moment that signals both ambition and technical mastery, China has unveiled the world’s longest expressway tunnel. The project cuts through the unforgiving Tian Shan Mountains. It does more than set a record. It transforms how people, goods, and regions connect across northwestern China.

Inside the Tian Shan Shengli Tunnel

The newly inaugurated Tian Shan Shengli Tunnel stretches an extraordinary 22.13 kilometres. It runs directly beneath a major expressway in the Xinjiang Autonomous Region.

The tunnel features two separate passages. Each passage carries two traffic lanes. Vehicles can travel at speeds of up to 100 kilometres per hour, ensuring smooth and uninterrupted flow.

From Hours to Minutes

Before the tunnel opened, crossing this mountainous route was slow and exhausting. Drivers often spent several hours navigating dangerous terrain.

Now, the same journey takes just 20 minutes by car. The change marks a dramatic improvement in daily travel and logistics.

A Backbone of Regional Connectivity

The tunnel forms a key section of the Urumqi–Yuli Expressway. This highway links northern and southern Xinjiang, regions historically divided by geography.

By bridging this divide, the tunnel strengthens public transport and boosts commercial movement. Businesses can now move goods faster and more reliably.

Engineering Against Nature

Carving a tunnel of this length through the Tian Shan range posed extreme challenges. Engineers faced harsh weather, seismic risks, and complex rock formations.

Yet the project advanced steadily. Its completion reflects China’s growing confidence in large-scale infrastructure under difficult conditions.

Economic and Strategic Impact

Beyond convenience, the tunnel carries long-term economic weight. Faster routes reduce transport costs. They also attract investment and tourism.

For Xinjiang, improved connectivity means deeper integration with national markets. It also supports regional development goals.

Analysis: More Than a World Record

This tunnel is not just a headline-grabbing achievement. It represents China’s broader strategy of using infrastructure to overcome geography.

By shrinking distance and time, Beijing continues to redefine what is possible in remote regions. The Tian Shan Shengli Tunnel stands as a symbol of that intent.
