Key features
  • An upgrade from a generally two lane to a four lane divided road with central median
  • A wide central median will allow for future widening to six lanes, if required in the future

  • Designated turning lanes, and bicycle and pedestrian crossing provisions at traffic lights
  • Bus priority lanes at traffic lights and indented bus bays

  • Improved safety for motorists by:
    • New intersections with traffic lights for access to precincts
    • A central median that separates opposing traffic flows
    • Turning lanes at intersections
