Burrows Road Tunnel
Abergeldie constructed an underground cable tunnel beginning in Campbell Road, running below Burrows Road, and finishing at the Energy Australia (EA)/ Transgrid substation in Alexandria. The tunnel carries 6 x 132kV circuits.
The project featured a launching shaft, an 87m long, 2800mm diameter, pipe jacked tunnel and a receiving shaft. The receiving pit featured 2 stages of construction, a temporary shaft to allow for the removal of an EPBM and further modifications to construct the final pit which sits within the EA boundary of the new substation.
