Pyrmont Bridge, Sydney

Pyrmont Bridge spans Cockle Bay in Darling Harbour, linking the city centre with the suburb of Pyrmont. Completed in 1902, it was one of the first electrically operated swing bridges in the world, designed by engineer Percy Allan of the New South Wales Public Works Department. Constructed from steel and sandstone, the bridge features a central swing span that can rotate to allow ships to pass—an innovation that symbolised Sydney’s early 20th-century embrace of engineering progress and maritime commerce.

Originally built for road and tram traffic, the bridge played a key role in connecting the industrial wharves and warehouses of Pyrmont with the heart of Sydney. After closing to vehicles in 1981, it was restored and reopened as a pedestrian and cycle bridge, forming the main crossing through Darling Harbour’s redeveloped precinct. The swing mechanism remains operational and is still demonstrated regularly, providing a glimpse into the bridge’s original function and mechanical ingenuity.

Today, Pyrmont Bridge serves as both a heritage structure and a vital public walkway, lined with flags and offering panoramic views of the harbour, city skyline, and waterfront attractions. Its sandstone pylons and riveted steelwork have been carefully preserved, while modern lighting highlights its architectural details at night. Surrounded by cafés, museums, and regular ferry traffic, the bridge remains a practical link that reflects the area’s history, engineering, and everyday use on Sydney’s working harbour.
