Completed in 2016, The Gap and Natural Bridge reopened after a $6.1m upgrade at Torndirrup National Park. The cantilever stretches 10m out off the cliff over the Southern Ocean so tourists can feel the ‘full force of nature.’The scope was to Pickle and Passivate 2205 duplex stainless steel structural beams to be bolted to the rock as per ASTM A380 and ASTM A967.
