The Logan Motorway supports the movement of over $1 billion in freight each day and is a key transport corridor across South-East Queensland providing access to the Brisbane Airport and Port of Brisbane.
An estimated 210,000 trips are made on the Logan Motorway every day, however congestion on the motorway is worsening and significantly impacting productivity and road safety.
The Logan West Upgrade reference design was released in August 2026. View the reference design on the Logan West project website.
The project design will continue to be refined through the detailed design phase and we'll continue to gather feedback throughout this process.
The Logan West Upgrade project aims to provide congestion relief and reduce travel times while improving road safety. The current scope of work includes:
- an additional lane in each direction along the Logan Motorway between Centenary Motorway and the Mount Lindesay Highway
- an additional lane westbound between Boundary Road and Formation Street
- simplifying the Formation Street interchange to reduce motorway weaving and to cater for growing capacity
- upgrades to some off and on ramps along the project corridor to support smoother traffic flow and reduce congestion
- motorway enhancements to allow improved access for over-dimensional vehicles
- planned use of new smart motorway technologies.
Most of the land required for the upgrade is within the existing motorway corridor. Upgrades included in our reference design can be delivered without any private property acquisitions, ensuring the community gains the benefits of improved safety and reduced travel times without the disruption that acquisitions can bring. There will be some land acquisition from Local and State Government to deliver the project.
Once planning is complete, the Queensland Government will consider the proposal and Transurban will work with Government to agree on a suitable funding model.
Once approved, construction is expected to be completed before the 2032 Brisbane Olympic and Paralympic Games.
