Overpass project on road to completion

More than 60 percent of works have been completed on a large landmark road project in the Northern Territory indicating it may be ahead of schedule.

The $165 million Tiger Brennan Drive and Berrimah Road overpass project east of Darwin commenced on 25 November 2023.

In addition to building the overpass bridge, the project includes demolition of existing road infrastructure, construction of fill embankments, installation of major culverts, pavements, street lighting and a signalised intersection.

According to NT Infrastructure Minister Joel Bowden, extensive works have been undertaken to create new lanes for Tiger Brennan Drive, the Berrimah Road overpass structure, and the high fill embankments.

In the coming months, key works include earthworks and construction of retaining walls on Berrimah Road, south of the existing Tiger Brennan Drive.

New on and off ramps will be progressively completed. It is expected the project will be finished later this year.

Mr Bowden said the project was providing plenty of work for construction workers.

“This project is also good news for jobs and investment here in the Northern Territory, with the project being delivered by local company, Sitzler, and supported by a host of local subcontractors and suppliers,” he said.

Sitzler was established in 1976 and has offices in Darwin, Adelaide, Canberra, and Maroochydore. It is very active in South Australia and the Northern Territory, with the bulk of its current projects in Alice Springs, Adelaide and in the Darwin region.
