China-Maldives Friendship Bridge connects islands

The China-Maldives Friendship Bridge, constructed by the CCCC Second Harbor Engineering Co, was opened to traffic on Aug 30, 2018, becoming the first cross-sea bridge in the Maldives.

The project encountered significant challenges during construction due to waves exceeding 3 meters in height and water currents of more than 1.5 meters per second in the area. In March 2016, a hard coral reef layer complicated the installation of the steel pipe piles for the approach bridge. The project team continuously refined their techniques through experience and data analysis, eventually succeeding in installing the piles. In the area extending from the shore into the sea, workers had to contend with waves while advancing the bridge's construction. Dozens of workers operated in shifts, welding during the brief periods of calm between waves. By the end of June 2016, they had completed the 400-meter approach bridge.

Installing steel casing for the central sea pile foundations also posed challenges. Large floating cranes swayed with wave-induced height differences of nearly 3 meters, while the wave causing the hook to swing up to 30 meters, which complicated lifting operations. By studying hydrometeorological patterns, the builders identified optimal "window periods" for lifting operations. On Dec 6, 2016, construction was completed, securely establishing the bridge on the coral reefs.

Seven years after its opening, the bridge has become a crucial engine for local economic and social development.
