Cars run through Shenyang’s de-nosing tunnel, located on Shenyang’s Second Ring Road. The structure is made of steel, and the transparent materials covering it can absorb noise brought about by speeding cars, which is expected to significantly reduce the traffic noise for residents neighboring the road.
