京杭大运河的建设历程如下：
1、京杭大运河始建于春秋时期。春秋战国时期开凿运河基本都是为了征服他国的军事行动服务的。
2、隋王朝在天下统一后即做出了贯通南北运河的决定，其动机已超越了服务军事行动的目的，因为此时天下已统一。
3、隋以后的历朝历代，至清朝后期，无论是大一统时期政权，还是分裂时期的政权，都注重运河的疏凿与完善，其动机无外乎经济、政治、军事等方面，充分利用运河漕运。
4、大运河开掘于春秋时期，完成于隋朝，繁荣于唐宋，取直于元代，疏通于明清。漫长的岁月里，经历三次较大的兴修过程。最后一次的兴修完成才称作“京杭大运河”。

隋炀帝开长拓宽，直到至元二十九年（1292）年，元世祖完成了京杭运河的全线贯通。
成为元、明、清时贯穿南北的大动脉，在交通运输中起着重要作用。
1949年以前只有其中一小段勉强维持季节通航，现江苏北段的400多公里河道千吨级驳
