Now more than 70 per cent complete, more than 4.5km of road deck has been installed across both tunnels, with a specialist machine lifting and installing more than 2,000 giant 24-tonne concrete segments to create the future road surface.

The removal of both Tunnel Boring Machines is also underway, with a 400-tonne crane moving into position to lift the final pieces of TBM Bella’s 15-metre wide cutterhead out of the outbound portal, and the dismantling of TBM Vida nearing completion.
