These bridges are connected by the pedestrian and cycle path across Heirisson Island that they carry to the East Perth and Victoria Park foreshores.

[1] The two bridges, built with 1,628 tonnes (3.6 million pounds) of steel and 3 kilometres (1.9 mi) of cabling,[2] are approximately 90 metres (300 ft) downstream of the Causeway.

The bridges are S-shaped and represent a Wagyl, the Noongar manifestation of the Rainbow Serpent in Australian Aboriginal religion and mythology.

[6] The bridge was announced on 26 August 2020, with an estimated cost of A$50 million,[7][8][9] jointly funded by the state and federal governments under the "Perth City Deal",[10][11] with the construction managed by Main Roads Western Australia.

[23] An additional $80M cost was revealed in the May 2024 state budget, for water main upgrades, toilet blocks, and landscaping around the bridge.
