Cranes are used in the construction of a bridge in the Shenzhong Link, a 24-kilometer-long sea-crossing link between the cities of Shenzhen and Zhongshan in South China's Guangdong Province. A major infrastructure project in China, the Shenzhong Link will have the capacity to carry up to 90,000 cars a day and reduce the travel time between Shenzhen and Zhongshan from two hours to 20 minutes.
