The city of Tianjin, China, is currently implementing a Haihe River area redevelopment plan to revitalize its downtown area. The Dagu Bridge is located in the center of the redevelopment area and is one of the first projects in this redevelopment plan. The city of Tianjin asked for a bridge that could be a new symbol of the city. The final design is a double arch that complements the surroundings. One of the arches is larger than the other; therefore, the bridge is called the Sun and Moon Bridges. The site poses several geometric restrictions with respect to construction depth, maximum allowable vertical slope, and navigation requirements. The final bridge scheme satisfies all those restrictions.
