Australian design, technological innovation and construction made it a source of pride for the people of NSW. The place has potential to yield information that will contribute to an understanding of the cultural or natural history of New South Wales. When completed the Pyrmont Bridge was regarded as a landmark in the development of Australian engineering skills and technological innovation, being favourably compared with the technical achievements of the recently completed Tower Bridge in London. The bridge's innovative design included; the size of the swing span and speed of operation; development of the timber bridge truss; caisson construction; design of the swing span bearings; and use of electric power. The design of the approach spans represent the highest level of development of the timber truss. The place possesses uncommon, rare or endangered aspects of the cultural or natural history of New South Wales. The timber approach spans demonstrate a rare example of deck type Allan trusses; there being no other known example.
