Xian is ranked as the second largest highway transportation hub in China, supported by five national highways of 345 kilometers (214.4 miles) and twelve provincial freeways of 266 kilometers (165.3 miles). Additionally, ten freeways have been constructed between the urban area and the districts and counties in Xian City. Any journey between each other of them takes no more than one hour.
