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 the Mount Lindesay Highway.

When completed, the project is expected to improve travel times, reduce congestion and improve road safety.

Why is the project needed?

Significant population growth and economic development within South East Queensland is increasing pressure on our transport network. If nothing is done to ease traffic congestion, average speeds across key sections of the Logan Motorway will reduce to 15km per hour during peak periods by 2031.

With an estimated 210,000 trips made on the Logan Motorway daily, and expected increases in traffic by 35% by 2041, the project is crucial in ensuring the motorway’s efficiency and safety for years to come.

Current project scope

• 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

• Planned use of new smart motorway technologies to provide real-time traffic updates

• Motorway enhancements to allow improved access for over-dimensional vehicles.
