The T2D Project involves the construction of two separate tunnels – the Southern Tunnels and the Northern Tunnels – that will be connected by an open motorway. The motorway and the tunnels will all have three lanes operating in each direction, with a combined total distance of 10.5km.

Southern Tunnels

  • Run between the open motorway at Darlington to just south of Anzac Highway in Glandore and provide key connectivity to Anzac Highway
  • Includes about 4km of twin three-lane tunnels

Open motorway linking the tunnels

  • Connecting to key routes such as Richmond Road and James Congdon Drive, it will provide critical east-west connectivity and links to key destinations such as the airport
  • Just over 2.5km in length

Northern Tunnels

  • Run between James Congdon Drive and the existing open motorway south of Grange Road
  • Includes about 2.2km of twin three-lane tunnels

When complete, more than 50% of the T2D Project will be tunnels.

  • Twin tunnels
  • 3 lanes in each direction
  • 80 km/h speed limit
