Just south of Rhodes, it changes name to Homebush Bay Drive and heads in a southerly direction, crossing M4 Western Motorway and changing name again to Centenary Drive, then over Great Western Highway in a short distance just south of Sydney Olympic Park.

[3] It crosses over Hume Highway at Strathfield South, where it changes name to Roberts Road, and continues south to Greenacre, where it diverts southeast and changes name again to Wiley Avenue, before meeting Punchbowl Road at Lakemba, New South Wales, where it changes name for the last time to King Georges Road and continues in a southeasterly direction.

[13] After 1964, upgrading projects were commenced, with the construction of new De Burghs Bridges over the Lane Cove River between Pymble and Ryde (1967).

The part of this route that passes through Strathfield town centre was very congested and also problematical to widen.

A major deviation of this part of the route was built between 1983 and 1998, relocating the arterial route to the west between Rhodes and Wiley Park, to bypass the Strathfield bottleneck and improve access to the Olympic Precinct at Homebush Bay.

Called the "Strathfield Bypass" at the time, the deviation route includes the new Homebush Bay Drive and Centenary Drive (named for the centenary of Strathfield Municipality), and an upgraded Roberts Road though Chullora and Greenacre, connecting to King Georges Road near Wiley Park.

As a major access route to Sydney Olympic Park, a grade-separated crossing was constructed at the M4 Western Motorway and Parramatta Road, at Flemington (1992) and the intersection with Australia Avenue and Underwood Road at Homebush (1998).

Grade-separated crossings were also constructed at M2 Hills Motorway at Macquarie Park (1997), at Victoria Road at Top Ryde (1998),[14] the Hume Highway at Chullora (1998), and the M5 South Western Motorway at Beverly Hills (2001).
