South of Adelaide, work is continuing to progress on the $120 million Majors Road Interchange project, with 18 girders now installed for the widening of the Majors Road bridge.
The girders range from 23 to 31 metres in length, each weighing between 8 and 14 tonnes. They were installed across four nights using a 300-tonne crane.
They will allow the existing Majors Road bridge to be widened from the current two lanes to six lanes, including two through lanes and a dedicated right turn lane, onto the Southern Expressway, in each direction.
SA Minister for Infrastructure and Transport Tom Koutsantonis said, “The installation of these 18 massive girders for the widening of Majors Road Bridge will increase its working capacity by four lanes.”
As well as increased bridge capacity, the Majors Road Interchange project will see the construction of new on and off-ramps for the Southern Expressway at Majors Road.
An important arterial road in the southern suburbs, Majors Road is used by around 13,200 vehicles a day. It’s anticipated to reach around 14,700 during peak times by 2036.
While the Southern Expressway sees approximately 74,000 vehicles per day between Darlington and the Reynella interchange.
The Majors Road Interchange project is jointly funded by the Australian and South Australian governments, which each contributed $60 million, and is expected to be completed at the end of 2025.
