A glass-bottomed bridge in China deemed as a record-breaker when it opened on August 20 has closed, media reports said. The record-breaking structure hanging over the Zhangjiajie Grand Canyon closed on Friday. "We're overwhelmed by the volume of visitors," a spokesperson from the Zhangjiajie Grand Canyon's marketing and sales department told CNN, explaining that the bridge was the main draw of the canyon. He added that the capacity of the glass bridge was limited to 8,000 visitors per day, but total demand was ten times as much. The famous bridge also focused attention on other scenic spots in the area. When asked if the bridge was cracked or broken, the spokesperson said "there was no problem", CNN reported. He also confirmed that there were no accidents. The six metre wide bridge stretches 430 metres over a 300 metre-deep valley between two cliffs in the stunning Zhangjiajie Park, said to have inspired the scenery for the sci-fi Hollywood blockbuster "Avatar". During the suspension, Zhangjiajie Grand Canyon plans to improve not only its infrastructure, including parking lots, but also its ticket booking system, customer service and other areas, CNN quoted officials as saying.
