According to an official, the bridge that collapsed recently in China in an accident that killed at least 41 people was made of rocks and concrete in order to achieve “harmony with the environment.”

“While the cause of the collapse is still unknown, a local official at the scene claimed that a ‘traditional and risky’ model of bridge, made of stone and concrete, had been chosen over a steel structure to ensure it remained ‘in harmony with the natural environment’,” the China Daily said.
