Linkfield Road Overpass upgrade

The department has been investigating options to reduce traffic congestion and improve safety and freight access for the Linkfield Road Overpass in Bald Hills.

Benefits

• Improves safety
• Increases capacity
• Improves network efficiency
• Increases traffic flow
• Reduces peak hour congestion
• Reduces interchange queuing
• Reduces travel time
• Contributes to economy
• Better active transport
• Reduces maintenance
• Improves ride quality

Key features

• Reduce congestion and traffic queue lengths
• Improve interchange ramp geometry
• Provide for active transport through the interchange
• Increased height clearance for higher loads.

Funding

This project is jointly funded by the Australian and Queensland governments. Project cost and timing subject to confirmation following market engagement and consideration. Investment ID 1160465

Design solution

The design for the upgrade of the Linkfield Road Overpass will help to reduce traffic congestion, improve safety, freight access and make more provision for active transport use.

Based on community feedback previously received, key features of the design include:

• upgrade of Linkfield Road to 4 lanes (2 lanes in each direction) between Gympie Road and Lacey Road intersections, and removal of existing Linkfield Road overpass to create a new overpass
• increase in the overpass clearance height from 4.7m to 6m
• upgrade of northbound and southbound entry ramps, and extension of southbound exit ramp length
• signalisation of northbound and southbound ramp intersections
• new separated pathway for eastbound pedestrians, riders and other users
• new on road cycle lane for westbound bike riders.

Current status

Preparations for early works on the Linkfield Road Overpass upgrade are underway.

These works will include relocating around 350m of an existing gas main, earthworks and other onsite preparation activities.

The main construction phase will commence once these works have been completed and the construction tendering process has been carried out.

Community consultation

Community consultation was undertaken by the department between 30 April and 28 May 2021, seeking feedback regarding issues, ideas and concerns around the overpass upgrade.

Sustainability

The Australian and Queensland governments are committed to manage the design and construction of the Linkfield Road Overpass upgrade to align with stakeholder expectations, including reducing the project's environmental footprint and building an increased network resilience to climate change.

Sustainable outcomes proposed will go towards demonstrating the project's commitment to contribute to net positive benefits for society and the environment. This was the focus of the project during design and will be during construction. The project is pursuing an Infrastructure Sustainability Council rating of ‘Excellent’ across both design and construction.

During the design and construction of this project we are:

• seeking to improve our environmentally sustainable practices to ensure a robust and adaptable transport network
• implementing effective management systems for workplace health and safety, environment, sustainability and quality management
• reviewing current generational needs while minimising environmental impacts for our future generations
• improving the provision for active transport though the interchange
• improving the east-west connectivity on Linkfield road
• minimising disruption to traffic during construction
• supporting and being responsive to the needs of stakeholders and the local community
• minimising negative impacts on the environment associated with the project
• maintaining quality of air, water and land by mitigating harmful emissions
• reducing energy, water and waste during the design and construction phases
• engaging suppliers and sub-contractors who can demonstrate environmental credentials.
