F6 extension


There is no motorway standard route between the Sydney motorway network and the M1 Motorway at Waterfall. Demand for road travel along this corridor is high and the arterial network is at capacity during peak periods. The three crossings of the Georges River, which together accommodate almost 200,000 trips per day, are at or close to capacity. These problems lead to long travel times, both because of slower speeds and intersections on arterial roads, and congestion.

The 2015 Australian Infrastructure Audit identified the Sutherland–Ryde/ Parramatta corridor as the fifth-most congested in the greater Sydney area in 2011, and forecast to be the sixth-most congested in 2031. The King Georges Road Corridor, between Princes Highway and the M4, was ranked as the second-most congested in 2011 and likely third-most congested in 2031.

Proposed initiative

The initiative proposes a motorway connection between the Sydney motorway network and the M1 at Waterfall.

The New South Wales Government has committed to construct Stage 1 of the link between WestConnex (New M5) and President Avenue at Kogarah.

Next steps

Proponent to complete business case development of remaining sections (Stage 3 of Infrastructure Australia’s Assessment Framework).
