Transportation [Edit this paragraph] Anhui Province has relatively developed transportation, of which the railway mileage is more than 2,500 kilometers, ranking first in East China. At present, there are more than 10 railways, among which the main railway lines are: Huainan railway, the main channel of Huainan coal transportation; Nanjing-Copper Railway connecting Jiangsu with Beijing-Shanghai and anhui-jiangxi railway; South from Suzhou Fuliji, south to beijing-shanghai railway, north to Fu Jia Railway connecting Jiahe Village in Jiangsu and Longhai Railway; Crossing the mountainous area in southern Anhui, entering Jiangxi through Xuancheng, Ningguo, Shexian, Huangshan, Qimen and other cities and counties, and reaching anhui-jiangxi railway where Guixi and zhejiang-jiangxi railway intersect; In Fuyang, it is connected with the Fuhuai Railway, and in the north, it is connected with the Beijing-Kowloon Railway of Longhai Railway. On the south bank of the Yangtze River, it ends in Tongling in the southwest, connects Wuhu in the north, connects Anhui and Jiangxi in the south, and connects Huainan Line in the northwest via Wuhu Yangtze River Bridge. Xuanhang line from Zhejiang to Hangzhou; The traffic artery connecting Anhui, Jiangxi and Hubei provinces and the He (Jiang) Ninth Line were completed and opened to traffic; Fu-Huai Railway connecting the coal bases of the two provinces, etc. There are also some local railways such as the Louvre Line. The national key railway Beijing-Kowloon line passes through Anhui, and Fuyang is its important hub. Beijing-shanghai railway, the north-south trunk line in eastern China, runs through the eastern part of the province; Longhai Railway, an east-west trunk line, passes through Xiaoxian County and Dangshan County in the north. The railway quality has also been greatly improved, and the railway hubs of Beijing-Kowloon, Beijing-Shanghai, Longhai, Huainan double-track and Wuhu have been built. The completed Hening Railway is located in the east section of the Shanghai-Han Rong Railway Expressway, which is an important part of the "four vertical and four horizontal" rapid passenger transport network in China. After completion, it can be connected with Anhe Railway, Hefei-Wuhan-Yucheng Railway and beijing-shanghai railway, which will add a fast and convenient passage for passenger and cargo transportation in the central and western regions and the eastern coastal areas of China, greatly shortening the time and space distance between Hefei and the Yangtze River Delta urban agglomeration, and benefiting Hefei and Nanjing, two provincial capitals. By then, it will only take 45 minutes for Hefei to go to Nanjing, 3 hours for Shanghai and 2 hours for Wuhan. The Hefei-Wuhan Railway under construction is a high-speed railway with a design speed of 250 kilometers per hour. Located in the east section of Ninghanrong Expressway, it is an important part of the "four vertical and four horizontal" rapid passenger transport network planned by the state. This section of railway is a national first-class double-track railway, which is connected with Xi 'an-He Railway, Wuyucheng Railway and beijing-shanghai railway, adding a fast track for the economic and cultural ties between the central and western regions of China and the eastern coastal areas. After the completion of the railway, it takes only 2 hours, 3 hours and 5 hours from Wuhan to Hefei, Nanjing and Shanghai by high-speed train. Hefei, Bengbu and Wuhu are international container loading and unloading points. The whole province has built a railway network extending in all directions with Hefei as the center. Highway traffic takes Hefei, the provincial capital, as the general hub and Huainan, Fuyang, Bengbu, Suzhou, Wuhu, Anqing, Xuancheng and Huangshan as the trunk lines, forming a highway network leading to cities and counties in the province. According to the second highway survey, by the end of 2000, the total mileage of highways had reached more than 65,000 kilometers, and more than 99% of towns and villages had access to highways. After the "Seventh Five-Year Plan", Anhui Province focused on improving the trunk highways from Hefei to various cities, and in 2002, a number of high-grade highways were built according to the national "two verticals and two horizontals" plan. Among them, Hefei to Nanjing, Tongling, Wuhu, Bengbu, Anqing, Hubei Huangshi and Lu' an were completed and opened to traffic; The newly-built high-grade highway leading to the famous scenic spots Huangshan and Jiuhua Mountain was partially opened to traffic; In addition, there are the national east-west passage from Lianyungang to Horgos, Xinjiang, and the high-grade highway from Bengbu to Jieshou. There are many national highways passing through Anhui, which constitute an important highway backbone. National highways 104, 105 and 106 to Beijing, 205 from Shanhaiguan to Shenzhen, 206 from Yantai to Shantou, 3 10 from Lianyungang to Tianshui and 3 168 from Xuzhou to Xixia. On the Huaihe River and the Yangtze River, Wuhe, Bengbu and Fengtai Highway Bridges, Huainan Highway and Railway Bridge, Tongling Yangtze River Bridge, Wuhu Highway and Railway Yangtze River Bridge and Anqing Yangtze River Bridge have also been built.
