Boorloo Bridge comprises two bridges: one on the East Perth side of Heirisson Island and a second on the Victoria Park side.

Boorloo Bridge is a pedestrian and cycle crossing comprising two cable-stayed bridges currently under construction that span separate channels of the Swan River in Perth, Western Australia. These bridges are connected by a pathway across Heirisson Island.

The crossing facilitates the linking of the East Perth side of the river with the Victoria Park side, and is located slightly downstream of the Causeway, the existing road crossing between the East Perth and Victoria Park sides across the island also carried over the river by two bridges. Construction began in March 2023, with an opening scheduled for 22 December 2024. The project was known during construction as the Causeway Pedestrian and Cyclist Bridges and was later named after the Noongar name for Perth, Boorloo.[1]

Design

The two bridges are approximately 90 metres (300 ft) downstream of the Causeway.[1] Separated by an approximately 257-metre-long (843 ft) path across Heirisson Island, the East-Perth-side bridge is about 163 metres (535 ft) long and the Victoria-Park-side bridge is about 280 metres (920 ft) long. The path carried by the two bridges across Swan River and that connects them across Heirisson Island is a 6-metre-wide (20 ft) segregated path. The bridges are S-shaped and represent a Wagyl, the Noongar manifestation of the Rainbow Serpent in Australian Aboriginal religion and mythology. There are three pylons in total. Two pylons are shaped to resemble Aboriginal digging sticks and one pylon is shaped to resemble a boomerang.[2]

Lighting display

[edit]

The bridge's stay cables – which are between 17 and 94 metres (56 and 308 ft) long – are intended to incorporate lights to display messages and images.[3][4]

History

[edit]

The Causeway's narrow footpath necessitated a dedicated pedestrian and cycling bridge; approximately 1,400 cyclists and 1,900 pedestrians use the Causeway per day.[citation needed][when?] The bridge was announced on 26 August 2020, with an estimated cost of A$50 million,[5][6][7][8] jointly funded by the state and federal governments under the "Perth City Deal",[9][10] with the construction managed by Main Roads Western Australia. The "Perth City Deal" had been preempted by the previous federal government.[relevant?][11]

Expressions of interest for the construction contract opened in February 2021.[12][13] Two proponents were shortlisted in April 2021,[14] and a consortium of Civmec, Seymour Whyte, and WSP Australia was named preferred proponent in March 2022, with the total estimated cost at the time being $100 million.[15][16] The contract was awarded in April 2022.[2] The Town of Victoria Park approved the bridge in September 2022, with the south-eastern end of the bridge occupying McCallum Park, which is owned by the Town of Victoria Park.[17][18] The bridge was approved by a Development Assessment Panel in December 2022.[19][20] The first sod was turned in March 2023.[21][22][23] Fabrication of the bridges' components was underway in Henderson, Western Australia, by November 2023.[citation needed] In the same month, riverine construction began.[24] An additional $80 million cost was revealed in the May 2024 state budget, for water main upgrades, toilet blocks, and landscaping around the bridge.[25] All major components of the bridges were in place by early August 2024, including all sixteen bridge modules and all pylons. It was also announced that the bridges were on track to open by the end of 2024.[26][27]

On 14 November 2024 it was announced that the bridges would open on 22 December 2024. The official collective name for the two bridges – Boorloo Bridge – was also revealed; Boorloo is the Noongar name for Perth.[1]
