I wanted to remind myself what the scoping report said about interchange points.
If you are wondering for your convenience:

"The non-stop Motorway component of the North-South Corridor will be directly connected to
intersecting arterial roads via interchanges located at Regency Road, Port Road/Grange Road/
Manton Street, Sir Donald Bradman Drive/James Congdon Drive, Anzac Highway, Cross Road,
Ayliffes Road /Shepherds Hill Road and Sturt Road. "
"Regency Rd Interchange
-Provides strategic access to the North-South Corridor for freight vehicles from surrounding industry and access to the intermodal terminal at Kilburn.
Port Rd/Grange Rd Interchanges
-Port Rd and Grange Rd are located in close proximity, so best functionality is to provide split diamond interchange.
Sir Donald Bradman Drive and James Congdon Drive Interchange
-The arrangement utilises James Congdon Drive for access to the city.
Anzac Highway and Cross Road Interchanges
-Functionality is provided by the split diamond interchange between the two intersections enabling
access between strategic freight, national land link and key feeder roads.
Tonsley Park/Ayliffes Rd/Shepherds Hill Road Interchange
-Tonsley Park to become major centre with 25,000 trips per day using the interchange.
Southern Expressway (SEXY)/Flinders Drive Interchange

"R4 was split into two road project sections as it appeared too large and costly (significantly greater than $1B) to deliver as one project. An approximate midpoint was chosen between the split diamond interchange of James Congdon Drive and Sir Donald Bradman Drive. Splitting R4 at this location also unlocks transport benefits for each of the new road project sections by connecting major crossing arterial roads to the motorway. "
