About the project
The Tasman Highway Sideling Upgrade is a program of works between St Patricks River and Minstone Road, Scottsdale, aimed at improving safety, travel reliability and freight efficiency.
The program spans approximately 24.5 kilometres through the Sideling Range, where steep grades, narrow road widths, winding sections and limited overtaking opportunities can affect safety, travel times and freight movements.
Completed and planned improvements include upgrades to road alignment, lane widths and shoulders to support safer and more reliable travel, improve freight efficiency, and strengthen connections for local communities, businesses and visitors across north-east Tasmania.
Minstone Road to Fairfield Road
This section covers approximately 2 kilometres of the Tasman Highway south of Minstone Road, Scottsdale.
The detailed design is currently under review.
Tender advertising is currently planned for spring 2026.
Fairfield Road to Whish-Wilson Road
This section covers approximately 8.5 kilometres of the Tasman Highway between Fairfield Road and Whish-Wilson Road.
Design work is continuing to identify improvements that will support safer and more reliable journeys and improve freight efficiency along the corridor.
Whish-Wilson Road to Sideling Lookout
Works on this 4.5-kilometre section were completed in April 2024.
The upgrades included road widening, shoulder sealing and road alignment improvements to provide safer and more reliable travel for all road users.
Sideling Lookout to Corkerys Road Intersection
This section covers approximately 10 kilometres of the Tasman Highway between Sideling Lookout and the Corkerys Road intersection.
Following community consultation in 2025, we are assessing a range of options, including upgrades to the existing highway and alternative route options. This work will help identify the best approach to improve safety, travel reliability and freight efficiency for road users.
The assessment will inform future decisions about the preferred route and scope of works.
Community consultation
Community consultation was completed in 2025. Thank you to everyone who took part. Feedback received during consultation is helping inform planning and future decisions for the remaining sections of the Tasman Highway Sideling Upgrade.
Funding
This $120 million-upgrade is jointly funded by the Australian and Tasmania Governments.
