Is it full speed to Xi 'an? What is the specific route from Mianyang to Xi 'an?

It's not full speed. Starting from Mianyang to Xi 'an is not at full speed. First of all, the road from Mianyang to Guangyuan (that is, the place where Jianmenguan service station passes) is the whole high speed. If you go this way at night, I suggest you get off at Baolun, and then take 108 National Road to Guangyuan, because there will be traffic jams at the exit of Guangyuan Expressway at night. ), (that is, after Guangyuan stands out) You have to follow the 108 national road to the Ciyaodian toll station. (It needs to pass through Guangyuan City) After getting on the toll station of the porcelain kiln shop, it is the secondary road. However, be careful when driving. After all, it is a secondary road, and then all the way to the chessboard pass. It is recommended not to go to the chessboard pass at night, because there will be traffic jams at night and you will be lucky. Bad luck means that one night, if you are a car, there will be no traffic jam. ) After seven passes, I went out of Sichuan and then to ningqiang county, Shaanxi. After seven lanes, you can get on the West Han Expressway, about 10 km, and then you can go straight to Xi 'an. I am from Mianyang, and now I am in Guangyuan. Believe me, I'm familiar with this. I suggest you walk during the day, it's not easy to get stuck in traffic. ).
