Giant bridges in China, USA, Europe and Russia can withstand magnitude 8 earthquakes, wind 250 m / s, collisions with ships weighing 300 thousand tons and are designed so that drivers do not fall asleep while driving.
China is recognized as a world leader not only in car production and demand for them. The country is also leading in the construction of the longest road bridges. In October 2018, traffic opened on the longest sea ferry in the world, connecting Hong Kong, Macau and Zhuhai. The length of the bridge was 55 km. However, there are equally grandiose highways in the world.
