Project overview

The Queensland Government has approved Transurban Queensland’s $512 million Logan Enhancement Project to proceed to detailed design and construction.

As part of this approval, the final concept design is now available – this design was directly shaped by community and stakeholder feedback.

The final concept design will deliver greater benefits than the initial concept design delivering greater value for motorists.

The project offers a unique opportunity to unlock the potential of South East Queensland through improvements to network safety, efficiency and reliability, as well as future proof this critical economic corridor.

The Logan Enhancement Project is the first private sector proposal to be assessed and approved under Queensland Treasury’s Market-Led Proposal process.

CPB Contractors has been awarded the contract to take the project into detailed design and construction. Detailed design has now commenced, with construction anticipated to commence in mid-2017 and take approximately two years to complete.

Funding and delivery

The Logan Enhancement Project final concept design will deliver significantly greater benefits than the initial concept design, for a minor increase to the original project cost.

The project will be delivered at no cost to the Queensland Government. To pay for the project, toll points on the new south-facing Compton Road ramps will be installed to match those on the north-facing ramps, and there will be a moderate increase to truck tolls on the Logan Motorway and Gateway Motorway. The changes will take effect once construction is completed in mid-2019 and the benefits of the project start to be realised.
