Bridge to Tibet – WoW
On the road to Spiti Valley there are many bridges now crossing the might Sutlej river. This was once the route taken by the Tibet highway that was cut into the mountain side on the right bank of the Sutlej. At that time bridge building was not possible over this kind of terrain. Parts of the old highway can still be seen high above the new road. The bridges have been washed away many times in the last decade by flash flooding from a side valley tributary river. Sometimes flooding is the result of glaciers retreating in China and the resulting deluge takes out many bridges.
