On January 14, 2026, the construction of all 394 pile foundations for the sea-crossing section of the central main channel of Dalian New Airport was completed.

The pile foundations in this sea area serve as the "anchor" of the entire sea-crossing bridge, directly affecting the overall stability and long-term durability of the bridge.

Since the start of construction, the project team of CCCC Second Harbor Engineering Co., Ltd. has overcome challenges such as the wide distribution of karst caves and complex karst forms in the sea area, and has organized construction scientifically and carried it out meticulously, effectively ensuring project progress and quality.
