As the central city in the Yangtze River delta, the biggest advantage of Nanjing lies in the fact that it is an integrated transportation hub with land, sea and air routes.
Nanjing has the Lukou International Airport, and has planed the construction of Ma’an Airport in Liuhe District. Lukou International Airport is one of China's top ten airports, as well as China's fifth largest international cargo airport. It is also an air cargo center, a distribution center for China Postal Express and Logistics, and enjoys 144-hour visa-free entry at airports in Jiangsu, Zhejiang and Shanghai.
Nanjing South Railway Station, the largest railway hub in Asia, accommodates high-speed rails to and from six directions across China. With 55 million people travelling past it every year, Nanjing South Railway Station has a magnitude even larger than railway stations in Beijing, Guangzhou and Shenzhen. Now it has trains shuttling on Nanjing-Central Europe Line and Nanjing-Central Asia Line.
Nanjing is located in the lower reaches of the Yangtze River golden water course. The 12.5-meter waterway makes Nanjing the deepest sea harbor on the Yangtze River as well as the most direct and convenient sea access for regions in the upper and middle reaches of the Yangtze River. Nanjing Longtan Port is the largest inland container port in Asia, with access for 100,000-ton ships.
It also tops China as to the density of national highway network, with 16 expressways connecting China's major cities.
