The Minns and Albanese Labor governments are one step closer to upgrading one of Sydney's busiest intersections, with a new design unveiled for the $200 million Homebush Bay Drive and Australia Avenue intersection upgrade.
The new design replaces the existing roundabout with an easy to follow, signalised intersection, complete with additional lanes to ease congestion and keep traffic moving, particularly during peak periods and major events at nearby Sydney Olympic Park.
Following comprehensive traffic and environmental investigations, a layout has been developed that minimises impacts on Bressington and Bicentennial parks while delivering a safer, more efficient connection for everyone who walks, rides or drives through the precinct.
Community consultation on the previously proposed Diverging Diamond Interchange solution was supported by only 25 per cent of respondents due to concerns about the complexity, unfamiliarity and safety of this design.
The Australian and NSW Governments are each investing $100 million in this $200 million upgrade.
Work has now been completed on the project's Review of Environmental Factors (REF), which evaluates the environmental and community impacts of the revised design.
The community is being invited to provide feedback on the REF and the revised proposal, which has now been progressed to concept design, between 2 December and Sunday 18 January 2026.
The upgrade is set to benefit tens of thousands of people who use this intersection every year, with 5,000 vehicles traveling through the roundabout per hour during peak periods.
The upgrade comes after interim safety improvement work which was completed at the roundabout and Homebush Bay Drive on ramps in December 2024.
This work has led to improved short-term traffic flow and road safety, especially during peak periods and special events.
Work included installing new traffic loop detectors, 12 new roundabout operating signs and advanced warning signs at the roundabout and Homebush Bay Drive off ramps.
A pedestrian crossing was also relocated to a new, safer location on Australia Avenue and upgraded with a pedestrian fence.
This interim investment was delivered to improve safety at this key location while the major upgrade solution is developed, which will also address future growth in the area.
Construction of the major project is expected to start in 2027 and take about two years to complete.
