The Australian and South Australian governments have awarded a $600 million contract to deliver the Tram Grade Separation Projects (TGSP) to an Alliance comprising constructors McConnell Dowell and CPB Contractors, and designers Arup, Mott MacDonald, and Aurecon.

The project involves removing three level crossings where the Glenelg tram line crosses Marion Road and Cross Road, Plympton and Morphett Road, Morphettville, rebuilding the existing tram overpass at South Road, Glandore; and intersection upgrades.

Virginia James, South Australia Leader, Arup said the contract win highlighted how the firm’s global experience and local expertise led to a growing track record of delivering significant transport infrastructure in the state.

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. Our successful delivery of major transport projects highlights our vision for integrated and efficient transport infrastructure, such as the Ovingham Level Crossing Removal Project and Oaklands Crossing Grade Separation Project.

Approximately 50,000 vehicles pass through the Marion Road and Cross Road level crossings each day. During the morning and afternoon peak around 30 trams also pass through, resulting in the boom gates being down for up to 20 minutes each hour. Motorists currently experience congestion and variable travel times, particularly during these busy peak periods.

Approximately 25,600 vehicles pass through the Morphett Road level crossing each day.

Removing these level crossings will:

  • reduce travel times for motorists, buses, freight and airport traffic
  • improve safety for local residents, motorists, pedestrians, cyclists and tram drivers
  • provide new, safer and more accessible tram stops with improved pedestrian access
  • improve connection and sense of community between the suburbs either side of the tram line
  • create new community open space for locals to enjoy.

As part of the project, the intersections at Marion Road and Cross Road and Marion Road and Anzac Highway will be upgraded to further relieve congestion and improve safety.

Site investigations to inform planning are underway. Major construction will start in late 2024 and the level crossings will be removed by the end of 2025. 

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.
