Significant population growth and economic development within South East Queensland is increasing pressure on our transport network.

The Logan Motorway is a crucial part of this transport network, connecting communities between Brisbane, the Sunshine Coast, Gold Coast and Ipswich.

More than 210,000 trips are taken on the Logan Motorway each day to get motorists to their destination safer and sooner and this number of trips is expected to increase by 35% by 2041.

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.

But by 2041, average speeds on sections of the Logan Motorway will reduce to 15km/hr per hour during peak periods.

Transurban’s Logan West Upgrade project aims to reduce congestion and improve travel times and road safety outcomes.

The current scope of work includes:

  • Adding an additional lane in each direction along the Logan Motorway between Centenary Motorway and the Mt Lindesay Highway, and an additional lane westbound between Boundary Road and Formation Street
  • Upgrading the Formation Street interchange to cater for growing communities and industrial hubs
  • Installing new smart motorway technologies
  • Increasing vehicle height capacity across the Logan Motorway to allow for over-dimensional vehicles.

If approved, the project is forecast to reduce travel times by up to 20 minutes during peak periods in 2031.

Around 6,100 vehicles will be removed from local streets including Progress Road, Inala Avenue, Springfield–Greenbank Arterial, Goodna Road and Johnson Road each day.

The project will inject more than $1 billion into the local economy during construction and create over $2 billion in additional productivity for the region over the next 20 years.

Around 850 local jobs will be created for Queenslanders through the project including a focus on women and First Nations inclusion in the construction industry.

Transurban is partnering with the Queensland Government to develop plans to upgrade approximately 10km of the western section of the Logan Motorway, between Formation Street and Mount Lindesay Highway

If approved, construction will commence in 2027 and is expected to be completed before the 2032 Brisbane Olympic and Paralympic Games.

If approved, construction is expected to be completed before the 2032 Brisbane Olympic and Paralympic Games.

Significant work has been undertaken to minimise property acquisitions.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 property acquisition can bring. There will be some land acquisition from Local and State Government to deliver the project.

Further information on tolling will become available as the project proposal progresses.

However, the Queensland Government and Transurban are pursuing funding options that have no toll increases associated with the upgrade project for all vehicles except trucks.

The Logan Motorway is an option for motorists if they want to save time and get to their destination quicker, however alternative free routes are available.

Motorists who choose the alternative free routes will also benefit from the project with around 6,100 vehicles removed from local roads each day.

The project will reduce its impact on the environment by minimising carbon emissions, using innovative design and construction practices, and reducing and re-using construction materials.

Our reference design proposes to retain existing fauna crossings and exclusion fencing along the project area where possible. Our reference design includes installation of additional fauna exclusion fencing where required to further support the safe guidance of animals from the road and reduce the risk of incidents.

We’ve also included measures to protect healthy local ecosystems and manage water quality in our reference design, such as grassed drainage channels.

While it is still early days and there is a lot of work ahead before the project is approved and construction gets underway, we have taken on board the community’s desire to minimise disruption

In August 2026, we released the Logan West Upgrade reference design.

Proposed upgrades in the reference design reflect input gather during initial consultation in late 2024. We’re encouraging the community to review the proposed reference design and provide any further feedback to the project at loganwestupgrade@transurban.com.

All upgrades as part of the Logan West Upgrade reference design are indicative only and subject to approvals. The design will continue to be refined through the detailed design phase and we'll continue to gather feedback throughout this process.
