A landmark bridge on the world's highest railway has been finished. The 928m-long bridge stands on the 1,118km Qinhjao-Tibet railway which will provide access to Tibet's capital Lhasa. The piers of the main bridge have been designed to resemble the legs of yaks - which are native to the Qinghai-Tibet plateau - and the approach piers look like the snow lotus plant which grows only above the snow line.
