Sunshine Motorway (Mooloolaba - Peregian), David Low Way to Yandina - Coolum Road, duplication, business case

The department is planning to duplicate the Sunshine Motorway, between David Low Way to just north of Yandina-Coolum Road.

The purpose of this project is to increase the motorway's capacity from 2 to 4 lanes, to accommodate future growth, enhance safety, improve connectivity, and increase efficiency.

During the planning phase, provisions for active transport, such as bike riding and walking infrastructure, have been considered. The project also involves evaluating improvements to the Yandina-Coolum Road roundabout and the School Road intersection.

The business case phase is an important part of the project, as it investigates the preferred option in more detail to evaluate the design, construction costs and construction staging.

Community feedback received during the preliminary evaluation phase will be used to further develop the preferred option during the business case phase.

The timelines for detailed design and construction have not been determined and will depend on the availability of funding and the prioritisation of competing infrastructure projects across Queensland.
