China builds green expressway from garbage

XI’AN, China: An expressway with much of its roadbed built from construction waste will open to traffic in northwest China’s Shaanxi Province in November, local transport authorities said Saturday.

With a designed speed of 120 kilometers per hour, the 122-kilometer expressway links Lintong District with Huxian County under the provincial capital of Xi’an. The expressway is the first in China to use construction waste as building material for the roadbed, said officials of the Shaanxi transportation department.
