Jagdalpur. The survey of the glass bridge to be built for tourism in Kanger Valley National Park of Bastar has been completed. The glass bridge to be built in front of Tirathgarh waterfall at a cost of about 5 crores will allow tourists to see the full beauty of the waterfall safely. During the rainy season, the Tirathgarh waterfall appears in its fierce form. At that time, tourists want to see it closely, but due to the danger, the department has banned going close to the waterfall. With the construction of the glass bridge, tourists will be able to see Tirathgarh closely even during the rainy season.
