Hobart Airport Interchange

Background

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. An initial concept design for the interchange has been created to facilitate the predicted growth in traffic, including increases 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.

The Department is undertaking a study on the Tasman Highway from Sorell to Hobart to identify ways to make further improvements.

Current situation

The initial concept design has been created. The project was advertised for tender in April 2019, and the successful tenderer was Hazell Brothers.

The successful contractor will be responsible for detailed design, and construction of the interchange.

The concept design includes:

  • 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

Major Development Plan

Have your say on the draft major development plan for the Tasman Highway Airport Interchange

The community are invited to provide feedback and comment on the draft major development plan for the Tasman Highway Airport Interchange.

Consultation is open from 5 - 25 November 2019.

The section of Holyman Avenue that is to be realigned is located on an area of the airport precinct that has been identified as Environmentally Significant in the Master Plan.

This triggers Section 89 of the Airports Act that requires a Major Development Plan to be prepared for the realignment.

The section of Holyman Avenue to be realigned extends from the Llanherne Drive roundabout in a north westerly direction to match the proposed new interchange at the boundary with the State Government owned road reservation.

The environmentally significant area relates to lowland grasslands. A total area of 0.91 hectares is directly affected by the realignment of which 0.16 hectares is on Commonwealth Land. The proposed mitigation is to preserve the remaining 3.7 hectares of grassland, which is within land owned by the Tasmanian State Government, under a formal management agreement in perpetuity.
