World's Biggest Borers Begin Digging New Chinese Link

This article describes construction on the 9km-long twin tunnels to Changxing Island, part of the Shanghai Yangtze River Tunnel and Bridge highway. Examples of the huge infrastructure expansion taking place in China, these tunnels are being bored under pressure beneath the river with 5.43-meters in diameter tunnel boring machines (TBMs), considered to be the largest in the world. The article also describes construction of the viaduct across Changking Island and the 10.3km-long twin box girder bridge to Chongming Island.
