Fremantle Rail Bridge Protection - Underwater Rock Mound {0817 01} by

TAMS is working on constructing an underwater rock mound to protect the Fremantle rail bridge. The works include the installation of 14,500 tons of limestone and armour rock to form an underwater rock mound designed to prevent vessels from colliding with the bridge.
This photo captures the dredge, Total Support and its mounted Hitachi EX1100 excavator, placing rocks into the mound. I was quite intrigued by this work as there was no obvious way the operator could see how the rock placement was going.
