Bo Ri Bridge - a little-known attraction for tourists. Located at a very low position beside Provincial Highway 217 from Ganzi County to Litang, it is easy to be missed if you don't pay special attention.
Bo Ri Bridge is known as the first bridge in Kham. It is on the Yalong River in Le'an Township, 36 kilometers away from the county seat, and Provincial Highway 217 passes by.
Bo Ri Bridge is 125 meters long, 3 meters wide, and has a span of 60 meters. It consists of three parts: the bridge body, the piers, and the bridge pavilion. The piers look like two solid bunkers from a distance, all of which are stacked with round fir, pebbles, and stone slabs. In the middle of the two piers, 4-6 logs are used to support the arch. The length of the logs increases gradually from bottom to top, forming two cantilever arms, and then beams are erected on the cantilever, bridge boards are laid, and railings are installed to form the bridge body. The "umbrella"-shaped structure stacked with stone slabs on the piers is the bridge pavilion. The most amazing thing is that the entire bridge does not use a single nail or piece of iron. Every joint is connected with wooden wedges, which is primitive and practical.
