The Flinders Link Project in South Australia has now completed 70 per cent of girder installations, with a total of 14 steel beam bridge girders being installed over the last three months.
A spokesperson from the SA Department of Planning, Transport and Infrastructure (DPTI) said construction works for the new Flinders Station is well underway.
The Australian and SA Governments are jointly funding the $141 million Flinders Link Project to construct a 650-metre extension of the current Tonsley rail line, including an elevated single track over Sturt Road, Laffers Triangle and Main South Road, linking Flinders Medical Centre and Flinders University to the passenger rail network.
A DPTI spokesperson said the girders form the base of the bridge deck as part of the elevated rail bridge structure and 180 pre-cast concrete deck panels are installed on top of the 20 steel beam bridge girders. Concrete is then poured over the pre-cast concrete deck panels to complete the bridge deck.
Installation of the steel beam bridge girders across and adjacent Sturt Road were recently installed from 21st to 24th February.
Installation of the steel beam bridge girders across Laffer Drive will be occurring this month, whilst the remaining steel beam bridge girders will be installed within the construction areas over the coming weeks.
Following completion of the girder installation, pre-cast concrete deck panels and concrete pours the new railway tracks will be installed directly on top of the concrete deck along the elevated bridge and approaches in the second quarter of 2020.
Gateway South, a joint venture between Fulton Hogan and Laing O’Rourke was awarded the design and construct contract for the Flinders Link Project.
A DPTI spokesperson said there are approximately 88 suppliers and 59 subcontractors working on behalf of the project.
Design of the new Tonsley Station is progressing and the entire project is expected to be completed in the second half of 2020.
