Building the Warrego Highway east interchange

The eastern end of the Toowoomba Second Range Crossing is at the Warrego Highway, Helidon Spa.

This interchange involves:

  • constructing a bridge over the Warrego Highway at Helidon Spa, with two eastbound lanes and two westbound lanes, enabling motorists to enter and exit the Toowoomba Second Range Crossing
  • closing the median break at the intersection of the Warrego Highway, Postmans Ridge Road and Twidales Road at Helidon Spa in late 2018 (due to the safety impacts of merging and weaving traffic at the Warrego Highway east interchange and right-turning traffic at the intersection). This closure will restrict all right turns at this intersection.

The Department of Transport and Main Roads has developed a solution to enable all turning movements within a short distance of the intersection, minimising the impacts on traffic that would have previously turned right at the intersection.


Construction updates

The first phase of construction works for the Warrego Highway east interchange has now commenced. This includes installing concrete barriers, building the new highway alignment, and undertaking earthworks, bridge piling, delivering and installing construction material and precast structure components.
