元代通州至大都(今北京)的通惠河于至元三十年(1293年)建成,从此,江南的漕船可以直驶大都城内的积水潭,标志着京杭运河最后贯通。通惠河虽然不长,但水源困难,比降过陡,因而必须兴修大批通航建筑物,其设计施工都是京杭运河比较困难的河段之一。明代由于通惠河上源引水工程废弃,加之城市改造,使通惠河通航只能到北京东便门外大通桥。因该河段航运十分艰难,首都的粮食大部分又恢复了陆运。自明永乐迁都北京后,经几次对通惠河的改造和治理,最后到嘉靖七年(1528年),在巡按直隶监察御史吴仲主持下, The Tonghui River from Tongzhou to Dadu (now Beijing) of the Yuan Dynasty was completed in the 30th year of Yuan Dynasty (1293). From then on, the water vessels in the south of Yangtze River can go straight to the Jishuitan in most of the cities, marking the final succession of the Grand Canal. Although the Tonghui River is not long, its source of water is difficult and steep, so a large number of navigable buildings must be renovated. Its design and construction are all one of the more difficult sections of the Grand Canal. As the Tonghui River source water diversion project was abandoned in the Ming Dynasty, combined with urban renewal, the Tonghui River navigation can only go to the Beijing East Gate outside the Chase Bridge. Due to the difficult shipping of the river section, most of the capital’s food was restored to land.
