China has many dangerous highways located on cliffs, which are often built due to geographic conditions and terrain constraints. These highways may be located on the edges of steep mountains, canyons or cliffs, and are often narrow, rugged roads that pose great danger to drivers and passengers. China is home to a number of magnificent cliff-on-cliff infrastructure projects, which often involve the construction of various infrastructures, including highways, bridges, ropeways, tunnels, etc., over mountain ranges, canyons, and steep terrain.
