青藏铁路楚玛尔大桥 Chumar River Bridge
Chumar River Bridge, 2565 meters long, was built for migratory Tibetan antelopes. The bridge's 78 bridge holes allow the Tibetan antelope and other wild animals to freely pass through. It is a key controlling project for the Qinghai-Tibet Railway. The two sides of the Chumar River are the main habitat and migration route for the Tibetan antelope.
