The Dalian Bay Undersea Tunnel, recently inaugurated in Dalian, China, is a groundbreaking infrastructure project enhancing the city’s connectivity.

Given its location in the northernmost part of China, the Dalian Bay Undersea Tunnel endures extremely cold temperatures and harsh climatic conditions. These factors impose stringent requirements on both the construction and lighting systems of the tunnel, demanding high durability and reliability to ensure safe and efficient operation.

To achieve this Sansi LED continues to leverage its comprehensive strengths in products, technology, and systems to provide an all-encompassing LED tunnel lighting solution for this major northern undersea tunnel.

A Gateway Beneath the Waves: The Dalian Bay Undersea Tunnel

The Dalian Bay Undersea Tunnel project spans a total length of 12.1 kilometers, encompassing both an undersea tunnel and a mountain tunnel, along with one underwater interchange and four land-based interchanges.

The undersea tunnel itself is 5.1 kilometers long, stretching from Dalian Suoyu Bay in the north to the Dalian Donggang Business District in the south.

Once operational, the tunnel will reduce driving time between the northern and southern coasts of Dalian Bay to less than ten minutes, significantly alleviating traffic congestion, promoting the integration of both sides of Dalian Bay, and contributing to the development of the Bohai and Yellow Sea coastal economic zones.

 

Advanced Construction Techniques

Constructed over four years, the tunnel showcases China’s leading position in underwater engineering. The installation of 18 massive immersed tubes involved advanced techniques, setting a new world record for immersed tube installation.

This project’s success reflects China’s capability to handle complex engineering challenges, demonstrating cutting-edge construction methods and stringent quality controls necessary for such an ambitious endeavor.
