The Australian and South Australian governments have awarded a significant $600 million contract for the Tram Grade Separation Projects (TGSP) to an Alliance comprising McConnell Dowell, CPB Contractors, and design firms Arup, Mott MacDonald, and Aurecon.
This initiative aims to enhance safety and efficiency along the Glenelg tram line by removing three critical level crossings at Marion Road and Cross Road in Plympton, and Morphett Road in Morphettville, while also rebuilding the existing tram overpass at South Road in Glandore.
Virginia James, South Australia Leader at Arup, emphasised the importance of the contract win, stating it reflects the firm’s combination of global experience and local expertise in delivering significant transport infrastructure.
“We’re immensely proud to be part of the Alliance delivering the TGSP, which is a critical component of unlocking key corridors in South Australia,” she noted.
The project is expected to alleviate congestion for approximately 50,000 vehicles and 30 trams that currently traverse the Marion and Cross Road crossings daily, which can lead to boom gates being down for up to 20 minutes each hour during peak times.
The removal of these level crossings is projected to yield multiple benefits, including:
- Reduced travel times for motorists, buses, freight, and airport traffic
- Improved safety for local residents, motorists, pedestrians, cyclists, and tram drivers
- Creation of new, safer, and more accessible tram stops with enhanced pedestrian access
- Strengthened community connections between suburbs on either side of the tram line
- Development of new community open spaces for local enjoyment
In addition to the level crossings, upgrades will be made to the intersections at Marion Road and Cross Road, as well as Marion Road and Anzac Highway, to further alleviate congestion and enhance safety.
Minister for Infrastructure and Transport Tom Koutsantonis remarked: “The removal of the tram level crossings on Cross and Marion Roads will reduce congestion and improve safety for everyone who drives, walks, cycles, or catches public transport through that area.”
Site investigations are currently underway, with major construction slated to commence in late 2024 and expected to conclude by the end of 2025.
This project is a vital step towards improving the transport infrastructure in South Australia, fostering economic growth, and enhancing the overall quality of life for residents.
