A bridge doesn't need to include the standard, gray concrete beams, cables, and deck. They can twist and turn and pop with color.

That's the philosophy behind the Lucky Knot bridge in Changsha, China, which was designed by Next Architects.

Spotted by Designboom, the whimsical pedestrian bridge actually has three bridges woven into one structure. Next Architects was awarded the project after their design proposal won an international competition in 2013, Michel Schreimachers, a partner at the firm, tells Business Insider. The steel bridge in Changsha's newly redeveloped city center was completed in late 2016.

The Lucky Knot stretches over a highway and the Dragon King Harbor River, sitting 78 feet above the river so boats can travel beneath it.

The 600-foot bridge is actually three separate bridges intertwined into one. Pedestrians can access it from eight street entrances.

The three walkways overlap at five points, which Schreimachers calls "moon gates."

The bridge's design mimics that of roller coaster tracks. Rather than just connecting the two sides, Schreimachers says, it also functions as a pedestrian playground.

The design team was inspired by the Chinese knot, which is how the bridge got its name.

In ancient Chinese folk art, the knot stands for luck and prosperity, Schreimachers says. The color red also symbolizes good fortune and joy.

Next Architects is known for creating unconventional bridges. The firm also built one in a Netherlands floodplain last year that can be submerged in water.

Like Next's other designs, the Lucky Knot is anything but ordinary.
