Overview

A $620 million project jointly funded by Australian (80%) and State (20%) governments as a key component of north-south corridor upgrade.

  3. Grade separation of the Main South Road/Ayliffes Road/Shepherds Hill Road intersection
  4. Main South Road (at grade) surface roads along both sides of the lowered motorway to provide connections to Flinders Drive, Sturt Road and most local roads
  5. Full free flow interchange at the Southern Expressway/Main South Road with dedicated ramps providing direct access to the new motorway and Main South Road.
