In the 1960s, the first [[Nanjing Yangtze River Bridge]] was completed, and served as the only bridge crossing over the Lower Yangtze in eastern China at that time. The bridge was a source of pride and an important symbol of modern China, having been built and designed by the Chinese themselves following failed surveys by other nations and the reliance on and then rejection of Soviet expertise. Begun in 1960 and opened to traffic in 1968, the bridge is a two-tiered road and rail design spanning {{cvt|4,600|m}} on the upper deck, with approximately {{cvt|1,580|m}} spanning the river itself.  Since then four more bridges and four tunnels have been built.
