What is the best self-driving route from Chongqing to Haikou?

No one has answered this question, so I won't ask myself. From Chongqing to Haikou, it is basically from north to south, and there is no need to take too many detours. On the way through Chongqing, Guizhou, Guangxi, Guangdong, Hainan. Among them, there are two routes to choose from on the road from Chongqing to Qiannan, Guizhou. The two routes are: first, Chongqing passes through Chongqing-Guizhou Expressway (a part of Blue Ocean Expressway), Zunyi, Guiyang and Duyun to Guangxi; 2. Chongqing goes to Guangxi via Baomao Expressway, Bai Yin Expressway, Daozhen Expressway and Duyun. Starting from Duyun, the two routes merged. Whatever the name, the later expressway was actually a part of the Blue Ocean expressway. Behind this road are Guixin (Guiyang to Xinzhai), (Hechi to Duan), (Duan to Nanning), Nanning Ring Expressway and Shenhai (Shenyang to Haikou). If you take the Blue Ocean Expressway from Chongqing, take the Guizun line to expand the expressway (Guizun double track) after Zunyi, with six lanes in both directions. It was just opened to traffic last year, and there are not many good cars on the road. Regarding the speed limit: most of Chongqing-Guizhou Expressway has a speed limit of 80, which is 120 for double track. The road sign of Duyun-Xinzhai section of Lanhai Expressway shows the speed limit of 80, but the electronic display shows the speed limit of1/kloc-0. I have repeatedly pressed 1 10 to run the speed limit, and the speed limit of most sections of Guangxi from Nandan to Duan is 65438. Although there are different routes to choose from between Chongqing and Guizhou, the distance between Chongqing and Haikou is basically the same, with little difference, about 1400 km. Normal driving time is about 20 hours, so pay attention to rest on the way. The expressway on the mainland side ends in Xuwen, Guangdong, and there is a section of urban road after getting off the expressway. There are two docks that can cross the sea, Xuwen Port and Yuehai Tiebei Port. Xuwen Port is easy to find, and there are many boats, but none of them are big. Parking on the boat is really a test of skill! There are fewer boats in the North Port of Guangdong Railway, but the boats are bigger, parking is convenient and the price is the same. It seems that the driver of a car is 430 or 450, I can't remember clearly. Passengers except the driver buy tickets to board the ship. It usually takes three to four hours to cross the sea. If there are many people in line, it's hard to say. After crossing the sea, if the ship is in Xuwen Port and arrives at xiuying port or Xingang, xiuying port is in downtown Haikou, and Xingang is far away from downtown, next to the south port of Guangdong-Hainan Railway. After arriving in Haikou, if you want to go to the east line, you can take the east section of Haikou Ring Expressway and connect with Haiwen Expressway (Wenchang) and East Line Expressway (to Ding 'an, Qionghai, Boao, Wanning, Lingshui and Sanya). If you want to go to Danzhou, Chengmai, Changjiang, Dongfang, Ledong and Sanya, you can take the western expressway. The expressway from the west line to Sanya is about100km farther than that from the east line, but there are relatively few cars. There is no charge in expressway, but the oil price is about one yuan more expensive than that in Chinese mainland. It is suggested to fill it in Xuwen. There are three self-driving routes from Chongqing to Haikou, namely Baiyin to Lanhai Expressway, Xiarong to Lanhai Expressway and Lanhai to Sanbei Expressway, among which Baiyin to Lanhai Expressway is the closest, Xiarong to Lanhai is the second, and Lanhai to Sanbei Expressway is the farthest. Here are three routes and the mileage and time of passing through the city along the way. The first is the Bai Yin-Blue Ocean Line. After leaving Chongqing, it passes through Inner Ring Expressway, Baomao Expressway, Bai Yin Expressway, Daoxin Expressway, Shanghai-Kunming Expressway, Blue Ocean Expressway, South Ring Expressway, Blue Ocean Expressway and Shenhai Expressway to haian port, Zhanjiang, xuwen county. The whole journey 1373 km takes about 15 hours and 45 minutes, passing through Zunyi, Hechi, Nanning, Qinzhou, Beihai and Zhanjiang. After arriving in haian port, xuwen county, waiting for the transition, the crossing time is about 3 hours. Second, the Xia Rong-Blue Ocean Line. After leaving Chongqing, it goes to haian port, xuwen county, Zhanjiang via Inner Ring Expressway, Blue Ocean Expressway, Guiyang Ring Expressway, Shanghai-Kunming Expressway, Xiamen-Chengdu Expressway, Blue Ocean Expressway, South Ring Expressway, Blue Ocean Expressway and Shenhai Expressway. The whole journey1382km takes about 16 hours and 45 minutes, passing through Zunyi, Guiyang, Hechi, Nanning, Qinzhou, Beihai and Zhanjiang. Third, the Blue Ocean-Three North Line. After leaving Chongqing, it passes through Inner Ring Expressway, Blue Ocean Expressway, Guiyang Ring Expressway, Shanghai-Kunming Expressway, Xiamen-Chengdu Expressway, Baomao Expressway, Guilin Ring Expressway, Quannan Expressway, Liubei Expressway, Sanbei Expressway, Blue Ocean Expressway and Shenhai Expressway to haian port, xuwen county, Zhanjiang City. The whole journey1555km takes about18h15min, which is the longest distance. It is suggested to choose the Bai Yin-Blue Ocean high-speed rail line, which is short and takes less time. The above suggestions are for reference only! 20 15 after I bought a house in Qionghai, Hainan, I drove myself from Chongqing to Hainan every year. The specific route is: depart from Nanping in Nan 'an District at 6: 00 in the morning, take Babin Road, cross Lijiatuo Huaxi Tunnel to Huatao Interchange, take G75 Blue Ocean Expressway, cross Tongzi Expressway, Zunyi Outer Ring Expressway (Gaoping and Xiazi), cross Meitan, Weng 'an, Fuquan, Duyun, Du 'an and Dushan, enter Nandan, Guangxi, and arrive in Nanning for accommodation that evening. When staying in Nanning, I choose a hotel that is close to expressway and convenient to get on and off through Ctrip. I'm staying at Tian Yun Hotel, Hairun, Nanning, 20 16. I got off at G75 Blue Ocean expressway, and then turned right at the first overpass on the city road. The price is not expensive, and you can park for free. 20 17 stayed at Nanning Jinzhonghuan Hotel near Nanning East Station. Also turn left from Nanning East Interchange. Hotel standard room price 198 yuan, free parking. There is a PetroChina gas station nearby. You can stop on the highway when you are on the road the next day. After leaving Nanning, take the Blue Ocean Expressway, cross Leizhou and Jixi, get out of G75, and take the national road to xuwen county. When you arrive in Xuwen county, you must fill up the fuel tank, or the oil price across the sea will be more than one yuan more expensive than that in the inland. In Xuwen crossing the sea, there are two options. One is to go to haian port or the nearby Hai 'an New Port, where there are many steamboats and start rolling. But the ship is small, and getting on and off the cabin needs to be tested. The second is to drive more than ten kilometers to the North Port of Guangdong-Hainan Railway. There are signs on the road. There are big ships everywhere in the port, with trains on the lower floor and cars and guests on the upper floor. The cabin is very spacious. I took the railway ship on 20 16, arrived at the dock on 12, and sailed at 12: 30, hardly waiting. However, there are fewer ships in this port. 20 17 arrived at the port at noon, but the sailing date is full, and it will have to wait until 2 pm. I had to immediately turn around and run to Hai 'an Xingang, where I got on the boat. The sailing time of the ship in Qiongzhou Strait is one and a half hours, and it takes half an hour to get on and off the ship. It takes about two and a half hours to add up. It's best to bring your own dry food and have lunch on the boat. On February 1, 2065438, I returned to Chongqing from Hainan, and also went to the south port of Guangdong-Hainan Railway first, intending to catch the 9: 30 ship. As a result, the flights before noon 12 were all full, so I had to rush to xiuying port again and take the boat flight of 10. My conclusion is that there are many ships in xiuying port, and the waiting time is short. There are fewer trains at the Guangdong-Hainan railway port, so it's luck to get on board. Bai Yin Expressway was opened at the end of 20 17. June 1 1 When I went to Hainan, I took the Bai Yin Expressway, from Nanchuan to Daozhen, Guizhou. The road condition is very good, nearly 30 kilometers than taking the Blue Ocean Expressway. I just drove here at 9: 30 last night. The starting road was really Dushan, Nanning, Nanning and around Guangzhou, and then I turned to the expressway in front of Qinzhou, and then I turned to g75 to Zhanjiang and Xuwen in Hai 'an. Whole sea crossing1450km. I think the 16-hour journey from Qinzhou to Guangzhou started from the first step and I tried it myself. Nanping and Qionghai both bought houses and drove there every year!
