CIMIC Group company CPB Contractors has been selected by the Federal and the South Australian governments to deliver the Tram Grade Separation Projects, in an Alliance with McConnell Dowell, Mott MacDonald, ARUP and Aurecon.
A $600 million contract to deliver the Tram Grade Separation Projects (TGSP) has been awarded to the Tram Grade Separation Projects Alliance (TGSPA) comprising constructors McConnell Dowell and CPB Contractors, and designers Arup, Mott MacDonald, and Aurecon.
Designed to improve safety, efficiency and the reliability of transport, the Tram Grade Separation Projects will also improve amenity, connectivity and liveability along the existing tram line from Adelaide’s CBD to Glenelg. Also key to this project are modifications to the existing overpass at South Road, with these works required to facilitate construction of the highly anticipated River Torrens to Darlington Project.
The Tram Grade Separation Project will generate revenue of approximately $212.8 million for CPB Contractors.
CIMIC Group Executive Chairman Juan Santamaria said: “These upgrades will be critical to supporting economic growth in South Australia and reducing travel times for motorists, buses, freight and airport traffic, while promoting sustainable urban growth and low emission, healthy transport choices for commuters.
“On completion, these works will foster a stronger sense of community between the suburbs of Adelaide, providing better, safer and more accessible tram stops with improved open spaces for the local people and visitors to enjoy.”
CPB Contractors Managing Director Jason Spears said: “CPB Contractors looks forward to further growing our partnership with South Australia’s Department for Infrastructure and Transport to safely deliver this important piece of infrastructure on time and on budget for the city of Adelaide.
“With over 40 years’ experience delivering city and region-shaping infrastructure in South Australia, we look forward to furthering our legacy in providing local employment and training opportunities, with a focus on diversity. Our expert team will continue our commitment to ensuring that social and economic benefits are maximised for the communities in which we work by prioritising the engagement of local businesses and suppliers, including Indigenous-owned businesses and social enterprises.”
The scope of work for the Tram Grade Separation Projects includes works at three main locations along the Glenelg Tram Line, works along the tram corridor, modifications of the existing tram overpass at South Road, replacement of the level crossings at Marion Road, Cross Road and Morphett Road with tram overpasses, intersection upgrades, tram depot upgrades at Glengowrie, and a temporary tram maintenance depot on Peacock Road on the edge of the CBD. The project will also comprise the installation of signalling upgrades along the tram corridor and the creation of new public spaces for the local communities.
About Tram Grade Separation Projects
The Alliance will remove the two level crossings where the Glenelg tram line crosses Marion Road and Cross Road, Plympton, and the level crossing at Morphett Road, Morphettville. The TGSP 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.
The Tram Grade Separation Projects will support approximately 1,115 jobs per year during construction. Major construction works will commence in late 2024 and the level crossings will be removed by the end of 2025.
Key project features
An overpass was determined in early 2023 as the best solution to removing these heavily congested level crossings. An overpass will:
- have the shortest construction time, minimising disruption to locals, as well as road and public transport users.
- significantly reduce the number of properties needing to be acquired – all properties identified as being required for the project have been directly communicated with
- improve connection and safety between the suburbs either side of the tram line
- provide new public open space under the tram line
- be delivered within the approved budget (an underpass cannot be delivered within the approved budget.
Intersection Upgrades
As part of the project, the intersections at Marion Road and Anzac Highway and Cross Road and Marion Road will be upgraded to further improve the flow of traffic, ease congestion and improve travel times and safety.
The Marion Road and Anzac Highway intersection upgrade includes:
- installation of two dedicated right turn lanes from Marion Road onto Anzac Highway
- two dedicated signalised left turn lanes from Anzac Highway onto Marion Road
- new and upgraded traffic signals, LED road lighting, line marking and drainage
