陈良宇
Urban traffic congestion and poor public transit had been a long-standing problem in Shanghai. Chen Liangyu was personally invested in the issue, and during his term in office Shanghai saw significant improvements to its transit system and transport infrastructure. As a result of the urban rail construction during Chen's term, the Metro had overtaken buses as the main transport tool for most Shanghai residents. Additionally, Mr. Chen oversaw the construction of bridges and tunnels on the Huangpu River, such as the Lupu Bridge. Opening several new arterial bridges relieved pressure from existing bridges and tunnels, thus easing traffic jams.
