Council unveils second machine for Legacy Way


Work on Brisbane’s Legacy Way tunnel is about to receive another boost with the unveiling of a second tunnel boring machine dubbed Joyce.

It will join its sister machine Annabelle which has so far dug half a kilometre of the 4.6 kilometre tunnel which runs from Toowong to Kelvin Grove.

Brisbane’s Mayor and company officials inspected the newest tunnel borer before it joins the existing machine, to continue the four kilometre journey from Toowong to Kelvin Grove.

The tunnel borers weigh in at nearly 3,000 tonnes each and together will chew through about 12,000 tonnes of rock every day.

Fernando Fajardo, Project Director: “20 metres per day with our boring machines would be an average, when we are in full production, doing that in the first month is a real milestone being achieved here.”

A conveyor belt transfers the crushed rock from beneath the city to the Mount Coot-tha Quarry.

The Council says this will ease congestion for suburbs close to the work site.

Graham Quirk, Lord Mayor: “96,000 truck-less movements will be on our city streets will be the outcome of this conveyor belt.”

It’s projected that once finished the tunnel will halve travel times from the Western suburbs to the City.

The Lord Mayor, Graham Quirk says that despite all the construction activity, traffic congestion has so far been minimal.

Graham Quirk, Lord Mayor: “I know, from a complaints point of view, we have had literally zero complaints from the motorists on the Western Freeway. They’re seeing this project with interest, I think they’re seeing this with anticipation.”

Council says around one million cubic metres of rock and dirt will be moved from the site by the time construction is completed in 2015.

Joyce will start work this Friday to help meet that deadline.
