Workers are starting to install one of three overpasses in Adelaide which will require hundreds of cubic metres of concrete for the Tram Grade Separations Projects.
520 cubic metres of concrete would be poured into the piles for the overpass along with the use of 1200 tonnes of structure steel, according to South Australia’s Department of Infrastructure and Transport.
The South Road Tram Overpass at Glandore is being rebuilt as a 95-metre steel arch bridge to accommodate the River Torrens to Darlington (T2D) Project lowered motorway.
It is part of Adelaide’s Tram Grade Separations Projects which comprise the removal of three congested tram level crossings, replacing them with new overpasses over Marion Road/Cross Road, Plympton, Morphett Road, Morphettville, and South Road, Glandore.
The Plympton overpass is made up of 52 beams and the bridge section is 13 spans, each around 35 metres-long. The whole bridge measures 730 metres including approach ramps.
The Morphettville overpass will be made up of 34 beams, reaching 380 metres in length. This includes two beams that will make up a smaller bridge, to be installed over the Sturt River to accommodate tram access to the Glengowrie Tram Depot.
Tram services are expected to resume before the school year starts in 2026.
The South Australia Government said more than a thousand jobs are being supported during the construction, and that construction activity in the state is at “record levels” with $21.08 billion forecast for 2025-26.
