Saigon River pedestrian bridge features unique palm leaf design

The pedestrian bridge spanning the Saigon River is entering its final construction stages, featuring a distinctive steel arch designed to resemble a water palm leaf. The structure includes a massive 33.2-meter wide roof intended to provide shade for pedestrians while presenting significant engineering challenges regarding wind resistance.

To ensure stability, designers conducted three wind tunnel tests to optimize the roof's curvature and arch structure, allowing the bridge to withstand wind speeds of up to 45 m/s. Dr. Kudo Hiroshi of Japan's Chodai Co., Ltd., the project's lead designer, noted that the large roof size required precise calculations to balance aesthetic goals with structural safety.

Beneath the water, the bridge relies on a massive foundation system covering nearly 1,800 square meters to protect against potential collisions from large container ships navigating the river. To maintain a sleek appearance, the heavy support piers are submerged, utilizing flower-shaped structures above the waterline to guide vessel traffic safely. Construction of these large concrete bases, such as TC1 and TC2, required specialized techniques to manage deep-water installation amidst strong currents and tidal shifts.
