Nanjing Qinhuai Bay Bridge / AND Office + NAN Architects

Nanjing Qinhuai Bay Bridge spans the banks of the Qinhuai River, the Beijing-Shanghai high-speed rail on the south, and the ring road on the north, connecting the city's CBD and ecological parks. It is an important gateway and urban landmark for the southern new city. The functional requirements and surrounding conditions of this bridge are very complicated. The entire line involves crossing expressways, crossing rivers, and underpassing railway viaducts, and needs to meet the comprehensive traffic requirements of machinery, non-passengers and pedestrians. Limited by the many restrictions on the plane and elevation and the basic engineering requirements of the main span of 157m, objective conditions have locked the bridge type in two configurations of tied arch bridge and single-tower cable-stayed bridge. Although many constraints avoid too divergent design starting points, they also bring difficulty in seeking features and new ideas.
