The highway built with salt in China is in Qinghai Province.

in the northwest, there is a magical long bridge, also known as a magical highway. Its building materials are not wood, masonry, steel bars or cement, but natural salt shells, and there is no pier or column. It is suspended above Chaerhan Salt Lake in Qinghai, the largest salt lake in China, with a length of 32 kilometers and about 1, feet, so it is called Wanzhang Salt Bridge.

due to long-term evaporation and less precipitation, the lake water has been condensed into a hard salt cover. Below the salt cover, which is tens of centimeters to more than one meter thick, are crystalline salt and intercrystalline brine with a depth of 1 to 2 meters. The highway is actually like a bridge floating on the brine, and the "Wanzhang Salt Bridge" comes from this.
