Sunshine Motorway (Mooloolaba - Peregian), West Coolum Road, upgrade interchange
The Queensland Government is progressing design for 2 new south-facing motorway ramps at West Coolum Road, Mount Coolum as part of a broader staged approach to upgrading the Sunshine Motorway
These ramps will improve connectivity and traffic flow, providing a new access point to the motorway between Yandina-Coolum Road and Pacific Paradise.
By providing an alternative route for motorists, the project is set to reduce traffic congestion on key local roads, including David Low Way and School Road/Yandina-Coolum Road intersection.
A concept layout has been developed to inform detailed design.

Funding
This project is a planned investment and is fully funded by the Queensland Government.
Investment ID: 3587043
Current status
Detailed design is progressing.
The project requires a referral under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) to assess potential impacts on Matters of National Environmental Significance. The EPBC Act referral was submitted on 8 May 2026 to the Department of Climate Change, Energy, the Environment and Water. The EPBC referral process takes time and needs to be completed before construction begins.
Consultation
Community engagement was conducted in 2021 and 2023, and feedback helped shape the concept layout for the south-facing motorway ramps.
Further engagement was undertaken in April and May 2026, inviting feedback on the concept layout to inform detailed design.
Collaboration with Sunshine Coast Council
The West Coolum Road interchange upgrade is being coordinated with Sunshine Coast Council-led projects that propose future connections from Suncoast Beach Drive and South Coolum Road to West Coolum Road. These projects will improve local road connectivity and enhance motorway access for the communities of Coolum Beach, Mount Coolum, Yaroomba and Marcoola.
