Thủ Thiêm 4 bridge design features four wave arches over the Saigon River

Thủ Thiêm 4 Bridge will rise over the Saigon River with four wave-like arches, a design inspired by the river's semidiurnal tides.

Ho Chi Minh City approved design TT42 by the TECCO1, T.Y.Lin International Engineering Consulting and CUBIC Architecture consortium as the top entry in the architectural competition. The bridge will run about 2.1 kilometers, linking Nguyễn Văn Linh Road in Tân Thuận with Nguyễn Cơ Thạch Road in the Thủ Thiêm new urban area.

The main bridge will use three continuous arch spans of 85, 180 and 85 meters. Box-section steel arches will combine with steel-concrete composite girders, cross-bracing and a pedestrian route to form a unified structure.

Pedestrian and cycling paths will begin at a lower level at both ends, then rise toward the center. The highest point will open views toward the Saigon River and the city's skyline. The four upper wave spans represent four tidal movements, while the pedestrian route serves as a “fifth living span” linked to the city's urban development.

The bridge will have eight lanes, including six motor-vehicle lanes and two mixed-use lanes, with a design speed of 60 kilometers per hour. City authorities have designated the project a priority investment to ease pressure on Tôn Đức Thắng Street, Nguyễn Tất Thành Street, Khánh Hội Bridge and the southern area.
