About the Logan Enhancement Project

Transurban Queensland’s $512 million Logan Enhancement Project includes widening sections of the Logan and Gateway motorways, improving key congestion hot spots (Logan Motorway/Mt Lindesay Highway/Beaudesert Road interchange and the Wembley Road/Logan Motorway interchange) and constructing new south-facing on and off-ramps on the Gateway Motorway at Compton Road.

The project is the first Market-Led Proposal to be approved in Queensland.

The project will improve safety and reliability, reduce travel times, enhance connectivity to key residential and business areas, and future proof the network.

CPB Contractors, a member of the CIMIC Group, is undertaking detailed design and construction of the project.

What’s happening now?

Construction of the project is now underway (commenced in June 2017), with detailed design now complete. Construction is scheduled to be completed in 2019.


The Logan Enhancement Project will unlock the economic potential of the Logan region as well as the business/freight hubs in Brisbane’s west and north.

It will deliver a safer and more efficient motorway network by relieving local traffic congestion, reducing travel times, and enhancing connectivity with other major road networks.

The project will support 1300 direct jobs during construction and generate around approximately $1.2 billion in economic benefits for Queenslanders over 30 years.

The project will deliver benefits to the economy, community, industry and environment, including:

  • enhanced safety – up-to 59% reduction in accidents as a result of the project due to less merging/weaving and stop-starting
  • travel time savings – the increased capacity in the road network provides shorter journey times and increased speeds in the network – up-to 90% reduction in travel times as a result of the project*
  • vehicle operating cost savings – less stop-start driving meaning lower fuel consumption and improved fleet productivity
  • reliability – more consistent journey times meaning motorists do not have to factor in ‘buffer time’ to their journeys
  • enhanced connectivity – new optional south-facing ramps will connect more motorists with the network, and reduce rat-running on Compton and Beaudesert roads
  • future proofing – the project will address current congestion and accommodate forecast traffic growth from arising from evolving residential and business corridors.

The Logan Enhancement Project is being delivered at no cost to the Queensland Government.

To pay for the project, there will be a moderate increase to truck tolls on the Logan Motorway and Gateway Motorway. The changes will take effect in mid-2019 and the benefits of the project start to be realised. Toll points on the new south-facing Compton Road ramps will be installed to match those on the north-facing ramps (the ramps will form part of the Kuraby toll point, and all vehicles will be tolled).
