Improving Mornington Traffic Flow

Tasmanian Government

Major infrastructure upgrades will see the Mornington roundabout replaced with traffic lights to improve road safety and traffic flow. The project will also include the construction of new ramps connecting the Tasman Highway with Gordons Hill Road.

The Albanese and Rockliff Governments have committed $100 million ($80 million and $20 million respectively) to the Mornington Roundabout Upgrade project, which will increase safety and efficiency through the known pinch point.

Objectives will be met by a multi-stage solution of improvements along the South Arm and Tasman Highways near Mornington.

The staged approach for planning, design and construction will be done over the coming years to minimise the impact on road users.

Work will start with building ramps to connect Gordons Hill Road with the Tasman Highway, allowing cars better access to Rosny from the highway while reducing traffic volumes at the Mornington roundabout.

Community consultation and design work on the ramps project will start this year, with construction planned for late 2026.

Once finished, other improvements near the Mornington roundabout will begin.

These future stages include:

The exact locations or layouts of these projects are yet to be decided, with further work required to develop design concept plans and engage with the community.
