Jiangxi enjoys a convenient transportation. With all major arteries being converted to expressway, the total mileage of expressways is more than 2,200 kilometers. Shanghai-Kunming and Beijing-Kowloon Railways cross the province, and other six trans-provincial expressways have been put into operation. There are five civil airports in Nanchang, Jiujiang, Jingdezhen, Ganzhou, and Ji'an, serving for dozens of domestic and international passengers. These expressways, airlines, together with crisscrossing railways, and water ports in Nanchang and Jiujiang have formed a convenient water-land-air transportation network.
