A ropeless bungee jumping attraction from the world’s highest road bridge has been suspended before its inauguration after videos of safety tests sparked fear on social media.

After making news headlines as the world’s highest road bridge, the Huajiang Grand Canyon Bridge was again in the news recently, this time for a controversial attraction that challenged daredevils to jump from the bridge into a rainbow-colored net to avoid falling into the Beipan River 625 meters (2,051 feet) below. Footage of the safety staff dropping sandbags of various weights into the net as part of safety testing went viral on Chinese social networks earlier this month, causing concern among the general public.
