Around 70 per cent of girder installations have been completed on the Flinders Link Project in South Australia, with a total of 14 steel beam bridge girders 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 $141 million project aims to extend the current Tonsley rail line by 650 metres and includes 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.
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 Laffer Drive will begin in March, with the remaining steel beam bridge girders to be installed 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.
