Workers prepare to install the last section of the Ganhe Super Bridge along the Wuhan-Guangzhou express rail in Xianning, Hubei province on June 18, 2008. The 3.42 km-long Ganhe Super Bridge is the most difficult part of the railway construction project. With an investment of 108 billion yuan ($15.69 billion), the 968-km Wuhan-Guangzhou railway, which is expected to be completed in 2010, can allow trains to run at speed of 350 km per hour. The train travel time between the two cities will be cut to only 4 hours from more than 11 hours currently. [Xinhua]
