Land bridge transportation means transportation from one seaport to another by railway across continents instead of by ocean ship. At present, there are two common routes for using land bridge transportation in the world. One is Asia-America-Europe land bridge, the other is Europe-Asia land bridge.Eurasia land bridge has obvious advantages over Asia-America-Europe land bridge due to its shorter distance, shorter transportation time and special freight rate. China started Eurasia land bridge transportation business in 1980. It mainly used the mode of railway-railway combined transportation. The comparison between using Eurasia land bridge and using shipping transportation from China to Northern and Western Europe shows that Euraria land bridge transportation can save time and get foreign exchange in time, and commodity turnover will be speeded up. According to the port layout and railway network structure, China's land bridge transportation projects are proposed. They are Suifenhe project, Dalian project, Tianjin project and Lianyungang project. The comparison of the four projects reveals that regarding to the total distance, Tianjin project is the shortest, but the distance covering China is shorter, and the transportation capacity of Beijing-Tianjin section is low. Lianyungang project has better geographical position and large attactive scope. The distance within China is the longest, but now there is 463 km of railway which have not been completed, and the transportation capacity is limited by Lanzhou-Xinjiang and Lianyungang-Lanzhou railway lines. From a long-term point of view, this project has a bright future.
