Updated: 2014-02-09

The Yellow River Under-crossing Project

The Yellow River Under-crossing Project is a crucial part of the middle line of the South-to-North Water Diversion project. In this project CGGC is the first to tunnel across the Yellow River (the second longest river in China) over a long distance using large-diameter shield machines. It is also the most enormous river crossing project in human history.
