These images of Pyrmont Bridge in Sydney, Australia are from the book 'Highway bridges of New South Wales' by John Bradfield.
One of the world's oldest surviving electrically-operated swing bridges, Pyrmont Bridge opened in 1902, and provided the main transport route between Sydney CBD and its growing western suburbs, whilst allowing tall vessels to access Darling Harbour through its swing feature.
