Warrego Highway Upgrade Program: Toowoomba to Oakey Duplication Stage 2 (Leesons Road to Kingsthorpe)


This is the second stage of the duplication of the Warrego Highway between Toowoomba and Oakey. Stage 1 was completed in July 2016.


Warrego Highway on Toowoomba's western outskirts, between Charlton and Kingsthorpe.


Construction by the Georgiou Group commenced in March 2017 and is expected to take 15 months to complete.



Improving motorist safety and capacity of the highway by providing separation between opposing traffic streams, intersection upgrades and new turning lanes to provide safe turning opportunities.


$160 million.


Downs South West Region

Project info

Stage 2 will duplicate the Warrego Highway from Leesons Road to just west of the intersection with Kingsthorpe–Haden Road and involves construction of a new 2–lane road parallel to the existing Warrego Highway. This new road will serve as the eastbound lanes. The existing 2–lane road will remain in use as the westbound lanes.

Stage 2 will:

  • make it safer to access the Warrego Highway from Gowrie Mountain and Kingsthorpe 
  • provide more overtaking opportunities for heavy vehicles on the Warrego Highway 
  • ease congestion on this section of the highway during peak travel times.

A significant feature of the project will be the construction of an overpass on the Warrego Highway at the intersection with Kingsthorpe–Haden Road and Gowrie Mountain School Road to improve safety.

Westbound drivers wanting to travel to either Kingsthorpe–Haden Road or Gowrie Mountain School Road will be able to turn left onto a new road linked to a roundabout just west of Zimm's Corner on the southern side of the highway. They will be able to proceed through the roundabout to continue south on to Gowrie Mountain School Road, or proceed from the roundabout to the overpass and join Kingsthorpe–Haden Road north of the highway.

The new road (eastbound) and existing road (westbound) will be separated by a 15m–wide grassed median to provide separation between opposing traffic streams. This means that some residents on the southern side of the highway will no longer be able to turn right on to the highway.

There will be no right turn from Linora Drive onto the highway. Instead, Linora Drive will be connected by a 720m long service road to Jannusch's Road, where the intersection will enable drivers to turn right onto the highway, and turn right off the highway when travelling from the west.

Community info

Travel times will be impacted by these projects. Local, regional and state-wide motorists and heavy vehicle operators using the Warrego Highway between Toowoomba and Miles will need to factor in extra travel time due to multiple Warrego Highway upgrade sites over the next 2 years.

The Warrego Highway Upgrade Program (WHUP) is a $635 million package of 15 approved projects between Toowoomba and Miles that are planned to be delivered between 2014 and mid-2019. The WHUP is funded 80% by the federal government and 20% by the state government.
