Works as part of this project include:

  • additional traffic lanes in each direction between Collier Road and Dunreath Drive

  • upgrades to the Guildford Road and Great Eastern Highway interchanges
  • a Principal Shared Path (PSP) with bridges, underpasses and local connections for cyclists and pedestrians
  • noise walls, lighting and amenity improvements

Additionally, a new Principle Shared Path (PSP) will be constructed on the western side of Tonkin Highway from north of Guildford Road interchange to Stanton Road with local connections.
