Alliance’s simultaneous construction in SA

Major construction on Adelaide’s Tram Grade Separation Projects is expected to start later this year with multiple overpasses to be built simultaneously.

The Tram Grade Separation Projects (TGSP) will be undertaken by the Tram Grade Separation Projects Alliance which comprises McConnell Dowell, CPB Contractors, Arup, Mott MacDonald, and sub-Alliance partner Aurecon, together with the South Australian Department for Infrastructure and Transport.

The TGSP Alliance will build a tram overpass in Morphetville in Adelaide’s south-west to replace a level crossing. The $200 million project will see a reduction in lengthy delays and improve road safety in the area.

The Alliance will also rebuild the South Road Tram Overpass at Glandore to accommodate the River Torrens to Darlington (T2D) lowered motorway, as part of the $15.4 billion T2D project.

As part of the TGSP, the intersections at Marion Road and Cross Road, Marion Road and Anzac Highway, and Morphett Road and Anzac Highway, will also be upgraded.

The level crossing removal projects and South Road tram overpass rebuild will support approximately 1115 full-time-equivalent jobs per year over the construction period.

The TGSP Alliance will complete the works on all overpasses simultaneously to fast-track construction time and reduce the impact on the community.

Major construction is expected to start in late 2024, with the level crossings to be removed by the end of 2025.
