After several weeks of challenging excavation, Tunnelling Solutions have broken through on the Arncliffe Pedestrian Link in Sydney.

With very poor ground conditions throughout, along with de-clutched canopy tubes under only 2.5m of cover - and trains running above them - the Tunnelling Solutions team did an excellent job in delivering this phase of the project.

The team will now focus on the Permanent Concrete Lining of the Tunnel and Portal Structure.
