The construction of a recreational glass walkway in Guizhou Province's Hongguoshu scenic area has been completed. The bridge is to open in early August. The construction for the 550-meter-long walkway started in March this year, with a total investment of about 7 million yuan (around 1 million U.S. dollars). The scenic area has a limestone cave that covers 10 square kilometers, waterfalls and a cave restaurant.
