ONE of the biggest sheds to be built in Australia is taking shape at Toowong in Brisbane’s west.

The six-storey-high, 89m long acoustic shed is being built at the Legacy Way tunnel worksite.

Lord Mayor Graham Quirk said the shed would house the tunnel boring machines and shield motorists and residents from noise and dust.

“I have a plan to deal with Brisbane’s traffic congestion and we’re getting on with the job of upgrading our most congested suburban roads and building vital new transport infrastructure,” he said.

Cr Quirk said the acoustic shed made of Colorbond steel and measuring 89m long, 77m wide and 29m high would be a temporary feature beside the Western Freeway.

It will be taken down late next year when the tunnel is completed.

“The acoustic shed is made with more than 1000 tonnes of structural steel, and in terms of floor space, is nearly 500 times bigger than your average backyard tool shed, so it’s no small feat to construct,” he said.

The tunnel boring machines (or TBMs) would operate 24 hours.

When completed the acoustic shed will be fitted with a series of travelling cranes, which will be used to assemble the two TBMs.

Legacy Way is the council’s 4.6km road tunnel from the Western Freeway at Toowong to the Inner City Bypass (ICB) at Kelvin Grove. Once open, Legacy Way will almost halve peak-hour travel times between the Centenary Bridge and the ICB.

Cr Quirk again acknowledged the Federal Labor Government’s support for the project through $500 million in funding.

Toowong Councillor Peter Matic said the location of the Legacy Way Tunnel Control Centre, which will be next to the existing Clem7 Tunnel Control Centre at Bowen Hills, would have less impact for residents.
