This photo taken on September 3, 2009 shows a section of a expressway connecting Sayram Lake and Guozigou being constructed above Tianshan Mountains in northwest China's Xinjiang Uygur Autonomous Region. The Sayram Lake-Guozigou Expressway, with a length of 56 KM, is very difficult to build up because it will get through Tianshan Mountains. The expressway is a section of the state highway from east China's Lianyungang to Horgos of Xinjiang, which is scheduled to be finished in 2010. [Xinhua]
