The new steel pedestrian bridge over the Dragon King Harbor River in Changsha is 185 metres long and 24 metres high. So far, it sounds like a large bridge, but nothing too extra-ordinary about it, right? Well, The Lucky Knot, as it's fittingly called, is designed with no apparent beginning nor end. It's an infinite loop, literally and metaphorically knotting three bridges together, while overlapping at five connection points. Designed with recreational, ecological and tourist activities in mind, it connects multiple levels at different heights (the river banks, the road, the higher-placed park as well as the interconnections between them).
"The shape of the Lucky Knot was inspired by the principle of the Mobius ring, as well as by the Chinese knotting art. In the ancient decorative Chinese folk art, the knot symbolises luck and prosperity," says John van de Water, partner at NEXT architects Beijing.
"The Lucky Knot is more than a bridge and a connection between two river banks. Its success lays in bringing cultures together, and in the fusion of history, technology, art, innovation, architecture and spectacle," adds NEXT architects Beijing partner Jiang Xiaofei.
