Warrego Highway west interchange

As part of work on the Toowoomba Second Range Crossing, a grade separated interchange will be constructed at the Warrego Highway, Charlton.

Building the Warrego Highway west interchange

This involves constructing:

  • two on-ramps, enabling motorists to access the Toowoomba Second Range Crossing in both directions
  • two off-ramps, enabling eastbound and westbound motorists to exit the Toowoomba Second Range Crossing
  • a bridge, taking the Toowoomba Second Range Crossing over the Warrego Highway
  • three signalised intersections to allow road users to safely turn in and out of the Toowoomba Second Range Crossing, Nass Road and Wirth Road.

Construction of the Warrego Highway west interchange will also involve permanently closing Willett Road at its intersection with the Warrego Highway. Access for local Willett Road residents and Toowoomba Speedway visitors will continue via Wirth Road.

Construction updates

Works on the Warrego Highway interchange at Charlton are progressing well, with bridge piers under construction in preparation for the delivery and installation of Super T girders for the two-lane, two-span bridge.

Intersection works at the Warrego Highway-Wirth Road-Nass Road intersection are planned for the coming months and once complete will allow motorists to safely access the new Nass Road decoupling yard and Willett and Wirth Road destinations through traffic lights.

The existing east and west bound heavy vehicle decoupling yards adjacent to the Warrego Highway at Charlton are expected to be closed in late 2017, following the opening of the new Nass Road decoupling yard.
