World's longest glass bridge abruptly closes after just two weeks

That didn't take long.

Just two weeks after China's Zhangjiajie Grand Canyon glass bridge opened to thousands of visitors, it had to close suddenly, with no re-opening date announced yet.

The 430-metre-long bridge, touted as the world's longest see-through bridge, is suspended 300-metres above a valley. Government officials shut it to visitors on Friday for an "internal system update."

Since the record-breaking bridge opened to the public on Aug. 20, it has received more than 10,000 visitors on a daily basis. According to local media reports, the attraction is only supposed to accommodate 8,000 people a day.

On their Weibo page, the bridge's operators posted a closure notice saying that they'll take the next few days to work on "software and hardware" updates that are necessarily to better

manage the influx of visitors.
