Trelawney Street Compound
Find out more


The Trelawney Street compound is being used for tunnelling. A 57 metre shaft has been excavated to support tunnelling along the main tunnel alignment. When tunnelling is complete, the shaft will be filled in and the acoustic shed dismantled.
A maintenance facility will be built to extract smoke from the northern portion of the tunnel in the rare event of a fire incident. This facility demonstrates NorthConnex’s commitment to the highest standards in safety and incident management.
