North South Bypass Tunnels/CLEM7

This project was built as part of the Lord Mayor’s “TransApex” vision to get traffic flowing more freely around Brisbane. Consisting of 4.8 kilometre twin, 2-lane tunnels (or tubes), it provides a river crossing 60 metres under the Brisbane River, linking Brisbane’s growing northern and southern suburbs. Excavation of both 12.4 metre diameter tunnels was completed with two Herrenknecht Tunnel Boring Machines. Nigel Pohio of BEM Group was contracted as General Superintendent (Tunnels) for this project.
