Tiger Brennan Drive and Berrimah Road Overpass

Tiger Brennan Drive is one of Darwin’s busiest arterial roads, with more than 20,000 vehicles using it each day. The introduction of the new overpass at Berrimah Road will help to improve traffic flow by separating local and through traffic, reducing congestion, and minimising delays.

This upgrade is particularly important for freight operators who rely on efficient transport routes, as well as for daily commuters navigating the area. By removing a key bottleneck, the project not only enhances road safety but also provides a more reliable and predictable journey for all road users, supporting the region’s growing transport needs.

The overpass addresses longstanding traffic challenges and creates a safer environment for all road users, including heavy vehicles and emergency services. By enabling faster and more reliable travel, the project fosters economic connectivity, particularly for industries reliant on efficient freight routes to the East Arm Wharf. For residents, reduced congestion during peak hours translates to valuable time savings and increased convenience, as well as a safer route to and from work.

“Tragically this intersection has previously been the location of multiple crashes and fatalities,” said Louise McCormick, CEO of the Department of Logistics and Infrastructure. “The project will create a safer, more efficient road network while supporting local economic growth.”

Local company Sitzler leads the construction, partnering with over 210 local businesses. To date, the project has engaged 1,710 workers, including 191 Indigenous workers and 48 apprentices and trainees, ensuring skill development and economic benefits for Territorians.

In May 2024, the Northern Territory Government, in collaboration with construction company Sitzler, invested $130,000 in the Soldier On charity to support veterans and their families in transitioning to civilian employment. This initiative aims to integrate veterans into the civilian workforce, recognising their leadership and discipline as valuable assets to the Territory’s economy.

Strategic investments in education, training, and partnerships with organisations like Soldier On underscore the government’s commitment to building a skilled and inclusive workforce, directly influencing project outcomes and community benefits. Prioritising workforce diversity has set a benchmark for inclusive employment practices in major infrastructure projects.

The overpass exemplifies cutting-edge engineering, incorporating features such as high-fill embankments, stormwater detention systems, and state-of-the-art drainage culverts to ensure resilience against environmental challenges. Sustainability has been a key consideration, with efforts to minimise disruptions and incorporate green technologies wherever possible.

“Safety and quality were of prime focus to Sitzler in the delivery of this game changing infrastructure element for Darwin and it’s community, together with clarity and ease of use by the road user,” said Sitzler Project Director, Michael Sitzler.

Department of Logistics and Infrastructure has prioritised stakeholder involvement throughout the project. Regular updates, alternative route planning, and consultation sessions have ensured that residents and businesses remain informed and supported. The project team’s responsiveness to community feedback has strengthened public confidence in the overpass’s long-term benefits.

“We engaged with industry early on in the project to make sure the design met their needs and expectations now and into the future.
As a key connector between the Darwin CBD and Palmerston, careful consideration was given to minimise impacts on road users while the overpass was constructed.” said Ms McCormick.

The Tiger Brennan Drive Overpass is not merely a solution for today’s traffic needs but a long-term investment in the Territory’s growth. By enhancing freight connectivity and improving commuter safety, it lays the groundwork for future economic and urban development.

The Tiger Brennan Drive Overpass stands as a testament to the power of strategic collaboration and innovation in transforming infrastructure challenges into community-driven successes.
