The Commonwealth and NSW Governments have unveiled a $100 million plan to upgrade the intersection
of Homebush Bay Drive, Australia Avenue and Underwood Road at Homebush, reducing travel times for
Sydney families and making major events at Sydney Olympic Park more accessible.
Federal Minister for Urban Infrastructure, Paul Fletcher said the project, which is being funded under the
Urban Congestion Fund, would improve travel through a particularly congested area around Sydney
As part of the upgrade:
Australia Avenue and Underwood Road will both be widened to allow more traffic to flow into this
more efficient intersection
Left slip lanes will be provided at all approaches and a U-turn lane installed on the Homebush Bay
Drive northbound approach will allow traffic flow back onto the southbound ramp towards the M4
Footpaths will be widened to become shared use pathways and on-road bicycle lanes will be
Refuge islands and coordinated user-activated crossings will be provided at all approaches.
The proposed intersection design known as a Diverging Diamond Interchange is the first of its kind in NSW
and was selected following the assessment of 12 options including roundabout improvements, overpasses,
underpasses, and various signalised intersection options that considered safety, efficiency, pedestrian and
cyclist connectivity, environmental impacts, community needs and cost.
The community is invited to comment on the proposal until Sunday 29 May. Once the consultation period
closes Transport for NSW will carefully consider all feedback received. A report summarising all feedback,
and Transport for NSW responses, will be published later in the year.
Subject to project approval, construction is expected to begin in 2025 and take about 18 months to complete.
