$163M NT overpass hits new milestone

The $165 million Tiger Brennan Drive and Berrimah Road overpass project in the Northern Territory has hit a new milestone, with 19 of 38 girders now in position as works continue on the bridge deck.

The project aims to improve the efficiency, safety and flow of 20,000 vehucles that travel through Tiger Brennan Drive daily.

The new overpass will carry Berrimah Road traffic over Tiger Brennan Drive, helping to divert and separate the flow of major traffic.

Works are also progressing on the second phase of the project, which includes the demolition of existing road infrastructure and construction of high fill embankments.

Traffic will be transitioned to the new alignment of Tiger Brennan Drive in stages once the bridge construction is complete and safe to allow vehicles to pass underneath with the project due for completion at the end of 2024.

“The bridge girders are a great visual of the project’s magnitude with the bridge abutments inscribed with artwork by local Larrakia artists Lorraine Williams and Natalie Quall. Each abutment retaining wall features 26 precast concrete panels with the largest panel standing eight metres high and weighing 11.6 tonnes,” Bowden said.

Sitzler Project Director, Rod Jeffrey said the installation of half of the project’s girders was a major milestone for the “significant project”.

“This substantial project is bolstering jobs and providing legacy experiences for companies and individuals alike, with over 180 local businesses already involved and more than 800 workers, including 110 indigenous workers and 40 apprentices and trainees,” Jeffrey said.
