A major engineering challenge has been accomplished with the installation of the first span of Super T girders on the viaduct of the Toowoomba Second Range Crossing (TSRC) project, linking Toowoomba with the Lockyer Valley.
He says the installation of the viaduct’s first 11 girders (span) is a major achievement.
“This sounds like a normal bridge job, but not when you consider the work is happening on the steep side of the Toowoomba Range and these Super Ts are up to 38 metres long, weighing up to 90 tonnes each.”
“The viaduct is being constructed along the escarpment between Wallens Road at Ballard and the New England Highway, using 5,000 tonnes of reinforcement and 26,000 cubic metres of concrete.
Federal Member for Groom John McVeigh also visited the site today.
“It’s great to see so many locals reaping the benefits of this project, including those involved in this girder lift today, and I’m looking forward to seeing the completion of this viaduct in 2018.”
Construction of the bridge deck will take approximately two years to complete.
The TSRC project is being funded on an 80:20 basis by the Australian and Queensland Governments.
