Statement of Significance
The bridge is a significant technical accomplishment, being large for its period of construction. It is similar to but smaller than the nearby Pyrmont Bridge across Darling Harbour, opened in June 1902. The Glebe Island Bridge was opened in 1903. Both Pyrmont and Glebe Island are large swing bridges, powered by electricity. Concerning Pyrmont, Allan said that, at the time of its opening: this bridge was said to be provided with the fastest and most up to date swing span in the world. The Glebe Island Bridge has swing spans of 29.1m and 29.1m, compared with Pyrmont, two at 34m. These spans have not been surpassed in Australia for a swing bridge and were not exceeded by any movable span until the first Tasman Bridge at Hobart (1943, 54.6m).

Description
The bridge carries a 12.2m wide roadway and two 1.5m footways. Its spans are 24.7m, 29.1m, 29.1m and 24.7m. The 24.7m spans are deck type Allan timber trusses. The two 29.1m swing spans rotate about a central vertical axis, being supported in the open position on a large diameter circular nest of rollers. These spans have deck type metal trusses of Pratt geometry, with a curved lower chord providing a larger depth at the central pier. The foundations are on piles and are finished in stone.
