Groundbreaking utility tunnel to debut in East China

The world’s first utility tunnel crossing two running subway lines was recently finished in east China’s Jiangsu Province. The tunnel was made using a 300-ton tunnel boring machine. The distance between the tunnel and the subway is just 4.356m, while the distance between the tunnel and the road is just 4.859m.

This utility tunnel is expected to be put into use before 2018.
