It's a knot-inspired bridge design which may well leave you tongue-tied.
Designers have unveiled plans for this pedestrian walkway which could provide multiple pathways across Meixi Lake in Changsha, China.
The unique design would have a 'diversity of routings', allowing pedestrians to cross the 150m-long bridge at different heights.
The bridge, which will be 24 metres high, has a knot design which refers to a Chinese knot from ancient decorative Chinese folk art.
It is also based on a Mobius strip, a famous mathematical surface which only has 'one side'.
The eye-catching bridge will be a key project in the Dragon King Harbur River development, and building will start next year.
It was the brainchild of Dutch architects NEXT, who won an international competition to design the structure.

'On the other hand it refers to a Chinese knot that comes from an ancient decorative Chinese folk art.
'The iconic appearance contributes to the developing identity of the area and with its lighting contributes to the whole light routing along the river. It provides both a view on the Dragon King Harbor River as well as Meixi Lake, Changsha and it surrounding mountains.'
