Hobart Airport Interchange
The comment period has ended, but you can still view the design and see community feedback received before the deadline via the online interactive display here.
The Tasmanian and Australian governments have committed $30 million to construct a four-lane interchange that will replace the Hobart Airport roundabout.
The new interchange will improve safety, reduce traffic congestion, and facilitate future increases of traffic.
The existing roundabout is currently operating at capacity – with delays and queuing often occurring during peak hour time periods.
Rapid growth in the residential areas of Sorell and the southern beaches as well as an increase in tourism numbers along the east coast and Tasman Peninsula, has contributed to more traffic throughout the area.
The annual average for daily traffic on the Tasman Highway near the airport is currently 27,000, and is predicted to grow by 2.8 per cent per annum to 47,000 by 2038.
The new interchange will improve access to the Hobart Airport, and has been designed to facilitate the predicted growth in visitor numbers, air freight transport, and commercial developments.
Cambridge, Seven Mile Beach, and the Hobart Airport precinct will be better connected and travel time reliability and traffic flow along the Tasman Highway will also be improved.
This design is used commonly in Australia and overseas in order to move high levels of traffic from a highway to adjoining towns and business centres without slowing traffic on the highway.
The Department will also be undertaking a study on the Tasman Highway from Sorell to Hobart to identify ways to make further improvements.
- Reconstruction and upgrading of 1.6 km of the Tasman Highway including extension of the dual carriageway
- A four-lane overpass, with the realigned Holyman Avenue and Kennedy Drive passing over the Tasman Highway
- Removal of the roundabout from the Tasman Highway
- A two lane off-ramp to the Hobart Airport
- A continuous flow on-ramp from the airport towards Hobart that will allow for future increases of airport traffic
- Realignment of local access roads
- Traffic lights to coordinate vehicles across the overpass. The traffic lights will be responsive to the volume of traffic

The project is jointly funded by the Tasmanian and Australian governments.
