Proposed tunnel solution

The proposed 7km two-lane tolled tunnel between Kedron and Carseldine will:

  • save users up to 32 minutes per day for a return journey in peak hour
  • improve safety and reduce pressure on suburban roads
  • enable better direct connectivity to the Gympie Arterial Road benefitting motorists between Kedron all the way to the Sunshine Coast
  • deliver a Gross Regional Product boost of more than $8 billion and generate around 1,800 direct and indirect jobs during construction.

Gympie Road will remain as a free alternative for motorists with improved travel times to be experienced along the surface due to an estimated 40,000 vehicles per day using the tunnel.

Gateway Motorway users will also benefit from the improvements to network capacity.
