Toowoomba Bypass

The Department of Transport and Main Roads (TMR) has delivered a second range crossing that takes heavy vehicle highway traffic around north of Toowoomba rather than through it.

The Toowoomba Bypass, previously known as the Toowoomba Second Range Crossing, reaches 41km from the Warrego Highway at Helidon Spa in the east to the Gore Highway at Athol in the west, via Charlton.

The Toowoomba Bypass plays a key role in accelerating the growth of regional Australia. Toowoomba is a key strategic link in the National Land Transport Network with almost half of all exports from the Port of Brisbane originating from regions accessed via the existing Warrego Highway Toowoomba Range section.

Of the 24,600 vehicle movements daily on the original crossing, 4400 are heavy vehicles. Up to 80% of these are expected to divert via the 41km-long Toowoomba Bypass improving the liveability for residents of the Toowoomba and Lockyer Valley areas.

The opening of the Toowoomba Bypass has meant some roads have changed names. 

  • The Toowoomba Bypass is:
    • the Warrego Highway (Route A2) from the Warrego east interchange (Helidon Spa) to the Warrego west interchange (Charlton) 
    • the Gore Highway (Route A39) from the Warrego west interchange (Charlton) to the Gore Highway interchange (Athol). 
  • The old Warrego Highway is now known as the Toowoomba Connection Road (A21) 
  • The old Gore Highway is now known as the Toowoomba Athol Road (A139)

Toowoomba Second Range Crossing


The 41km-long route reaches from the Warrego Highway at Helidon Spa in the east to the Gore Highway at Athol in the west, via Charlton.


  • Improved road and driver safety
  • Reduced travel times and greater travel time reliability
  • Avoiding up to 18 sets of traffic lights
  • Relieved pressure on Toowoomba roads by redirecting heavy vehicles away from Toowoomba's Central Business District
  • Removal of over-dimensional and all classes of dangerous goods vehicles from the suburban streets of Toowoomba
  • Increased freight efficiencies
  • Enhanced liveability for residents of the Toowoomba and Lockyer Valley areas.

This project was delivered under a Public Private Partnership (PPP) arrangement, with an indicative total cost of $1.606 billion. This includes an Australian Government contribution of $1.137 billion, with the balance funded by the Queensland Government.

Using the Toowoomba Bypass


The operation and maintenance costs of the Toowoomba Bypass are funded by tolls. Find out more about the toll point, toll costs and paying a toll

Heavy vehicles

All heavy vehicles traversing the range will be required to use the Toowoomba Bypass unless the vehicle has a local destination in Toowoomba or is travelling north or south via the New England Highway.

A local destination in Toowoomba is defined as a location within the mapped Blue Zone.

Destinations on the border of the Blue Zone (sections of Boundary Street, Bridge Street, Tor Street, Anzac Avenue, James Street, Canning Street and Drayton Connection Road as outlined in the map) will be required to use the Toowoomba Bypass.

The Toowoomba Bypass is primarily a freight route which has been designed and built to accommodate larger heavy vehicles (type 1 road trains, B-Triples and PBS Level 3 heavy vehicles).

The Toowoomba Bypass offers truck operators more options to configure their freight movements providing increased freight efficiencies and significant cost savings along this key regional freight route.

TMR is considering a range of compliance activities to manage access arrangements on the Toowoomba Bypass and existing Toowoomba Range (Toowoomba Connection Road). These range from industry information and education, to a combination of signage and on-road enforcement. Failure to comply with the mandate may result in fines and other penalties.
