Beijing to Hangzhou, China
The Grand Canal in China was constructed in sections from the 5th century BCE onwards, and became a unified means of communication for the Empire from the 7th century CE (Sui dynasty) onwards. By the 13th century it consisted of more than 2,000 km of artificial waterways, linking five of Chinas main river basins. Currently only the section from Hangzhou to Jining is navigable, and its course is divided into seven sections.
