Sunshine Motorway, Mooloolah River Interchange Upgrade (Stage 1)
The Sunshine Motorway, Mooloolah River Interchange upgrade will deliver a safe, efficient and effective transport network to meet the current and future transport needs of the Sunshine Coast.
In December 2021, GHD SMEC Joint Venture was awarded a contract to undertake design work for the Mooloolah River Interchange upgrade. This project will improve north–south travel between key residential, employment, health and education facilities to support population, economic and tourism growth in one of Australia's fastest growing regions.
In addition to improved transport capacity, reliability and safety, the Mooloolah River Interchange will also improve access and active transport connectivity for local communities in the Birtinya, Mountain Creek and Mooloolaba areas.
- Improves safety
- Improves network efficiency
- Better road access
- Reduces peak hour congestion
- Reduces travel time
- Contributes to economy
The first stage of this project will include a:
- new road overpass to provide a more direct and efficient connection from Nicklin Way to Brisbane Road at Mooloolaba
- new local road connection between Karawatha Drive at Mountain Creek and Brisbane Road at Mooloolaba.
These local road connections will separate local traffic from high-speed motorway traffic and reduce traffic weaving—a well-known issue at this interchange.
These first stage works need to be delivered first to enable construction of the project's future stages. These new connections will move local traffic away from the area and minimise impacts and inconvenience to road users and the broader network during future stages.
Future stages included in the planning layout will deliver:
- a new crossing of the Mooloolah River, connecting the Sunshine Motorway to Kawana Way
- the Mooloolah River Interchange, with connections to:
- the Sunshine Motorway to the west and north
- Nicklin Way to the south-east
- Kawana Way to the south
- an upgrade of the Sunshine Motorway from 2 to 4 lanes between the existing Kawana Way Interchange and the Mooloolah River Interchange
- a direct, safe and efficient connection for the Sunshine Motorway, north to west
- an additional northbound lane on the Sunshine Motorway between the Mooloolah River Interchange and the Buderim/Mooloolaba interchange.
The $320 million Stage 1 of the project is funded and will be constructed first.
The Queensland Government has committed $160 million to deliver Stage 1 of this project as part of the Queensland Transport and Roads Investment Program (Investment ID 2007574).
The Australian Government has committed $160 million to deliver Stage 1 of this project.
Funding is required to progress future stages to construction.

Mooloolah River Interchange flythrough
The Queensland Government is planning a major transport infrastructure project at Mountain Creek to make it easier, safer and quicker for people to travel on the Sunshine Coast, one of Australia’s fastest growing regions.
The Mooloolah River Interchange project will deliver a major new interchange, which will provide improved north-south connectivity and more efficient access to Maroochydore CBD, University of the Sunshine Coast, the Sunshine Coast University Hospital and health precinct, and the beaches.
It will also improve safety, by reducing crashes and traffic weaving.
Other improvements include an additional northbound lane on the Sunshine Motorway up to the Buderim-Mooloolaba Interchange and a new Sunshine Motorway overpass to provide a continuous high-speed connection for motorists travelling from north to west.
Access will be improved for local communities with a new Nicklin Way overpass connecting directly to Brisbane Road, new Mooloolah River crossings connecting the Sunshine Motorway to Kawana Way, a new link between Karawatha Drive and Brisbane Road and a new Sunshine Motorway overpass.
Active transport pathways are also included in the planning layout, to make it easier for people to ride and walk and a new signalised intersection will connect the Mooloolah River crossings to Kawana Way and southern areas of the Sunshine Coast.
The Mooloolah River Interchange project will provide new north-south connectivity between Maroochydore and southern growth areas, delivering a safer and more efficient transport network to meet the current and future transport needs of the growing Sunshine Coast region.

Design work is progressing and expected to be completed in 2023. Construction timeframes and start date for Stage 1 will be determined during the design phase.
From late March until June 2022, on-site field investigation activities will be completed at various locations, weather and site conditions permitting. These on-site activities will be used to technically inform the design and include geotechnical, road pavement, bridge, drainage structure and public utility infrastructure investigations.
Investigations are being conducted on land and in neighbouring river locations. Most are being conducted on state government-owned land. Some minor vegetation clearing is being undertaken to facilitate access to these locations. A wildlife spotter/catcher is present during the activities as required to mitigate wildlife impacts.
Further activities will take place from July to September 2022. Most works will occur between 6am and 6pm, Monday to Friday. However, due to the high volumes of traffic on certain roads, some works will need to be completed at night between 7pm and 5am, Sunday to Thursday.
Community consultation on the planning layout for the Mooloolah River Interchange was initially undertaken between 19 July 2021 and 27 August 2021. We reopened our online interactive map for further public feedback from 15 March 2022 to 29 April 2022.
Feedback submitted included design suggestions, road traffic noise impacts, active transport provisions, property impacts, traffic congestion, timing of the upgrade, environmental impacts, visual amenity changes and road user safety.
Community feedback is being considered as design work progresses. A preliminary design layout will be made available to the community later in 2022.
Impacts to local residents
Some property owners will be impacted by property acquisitions needed for the project. We are liaising directly with those property owners to ensure they are well-informed of the project, in line with our acquisition process.
We will liaise with residents and businesses located near the project, during the design phase and before construction—to inform them of any potential disruptions during construction and traffic changes once the project is constructed. We will minimise or mitigate these impacts as much as possible and will liaise with affected residents and business owners to provide advance notice where possible.
The design phase involves a wide range of technical design activities, including:
- road and bridge engineering
- geotechnical investigations
- hydrological studies and drainage design
- electrical and Intelligent Transport System design
- public utility infrastructure requirements
- environmental and cultural heritage studies
- active transport design and connectivity to local communities.
Road signs and markings
The design phase will identify a combination of directional and destination appropriate signage and linemarking to delineate travel directions. These will help direct people to ensure drivers are able to identify appropriate lanes and exits for their destinations. We use national standards and guidelines as outlined in the Manual of Uniform Traffic Control Devices for all signage considerations.
Integration with public transport planning
We are planning a Sunshine Coast transport network which supports multiple modes, including public transport. The needs and impacts of future projects such as Caboolture to Maroochydore Corridor Study and the Sunshine Coast Mass Transit project were considered as part of Mooloolah River Interchange planning. Planning confirmed there was adequate space to be protected for heavy rail (adjacent to the project) and this will be preserved as design work progresses.
