Launch Shaft Construction for Tunnelling
A massive launch shaft – 60 metres long, 20 metres wide and 16m below the ground will be excavated adjacent to Keelesdale Park between Black Creek Drive and Keele Street. The shaft will enable the tunnelling machines to be safely lowered and launched eastward in 2012. The tunnelling machines are so large that the parts will be lowered by crane and assembled on site.
