1About the project

The Hobart Airport Interchange will replace the existing Hobart Airport roundabout with an overpass.

The overpass will lift the Tasman Highway over Kennedy Drive and Holyman Avenue. This will allow traffic on the highway to travel through the intersection with reduced delays and improved access to and from the Hobart Airport.

The new overpass will make the road safer, reduce traffic congestion, and allow for future increases in traffic.

The design of the overpass is similar to the overpass constructed at the intersection of Huon Highway and Summerleas Road at Kingston.

  • On and off ramps from the highway will be used to access the Hobart Airport on Holyman Avenue, Kennedy Drive, and Cranston Parade.
  • Dual lane roundabouts will be built underneath the highway to efficiently and safely control the intersections.
  • Pedestrians, cyclists and other active transport users will have access to a dedicated shared path between Kennedy Drive and Holyman Avenue.

The contract to design and construct the interchange was awarded to Hazell Bros Pty Ltd

2Current situation

Start of Stage One works started December 2020.

These works will include:

  • constructing the eastbound off-ramp
  • westbound on-ramp
  • both roundabouts
  • and completing alterations to Kennedy Drive

Working times

Works will take place between 7:00 am and 5:00 pm, Monday to Saturday.

3Traffic Changes - May 2021

From May 2021, traffic at the Hobart airport roundabout will be diverted while the Tasman Highway is upgraded and a new bridge is built.

The number of exits from the roundabout will be reduced from five to four with vehicles diverted onto alternative roads:

  • Traffic heading to Hobart will need to exit the roundabout via Cranston Parade, which will then join onto the Tasman Highway.
  • Traffic heading to Sorell will need to enter the roundabout via Kennedy Drive and turn left onto the Tasman Highway.

Signs will be in place to guide road users and the diversions will be in place until early 2022.

To keep everyone safe, the speed limit through the project site will be reduced to 40km/h to allow road users to become familiar with the new arrangements. The reduced speed limit may affect travel times, so please allow 8 minutes extra travel time and follow the directions of traffic controllers and signs.

6Q&A's

Why do we need this project?

The existing roundabout has been operating at capacity. Predicted future population growth in the south east will continue to increase queuing and delays for vehicles at peak times.

Why has the design changed?

The new design improves traffic flow to and from Hobart Airport. It also reduces disruption to traffic flow during construction by keeping the existing roundabout operating for longer.

Does the new design require a new Development Application?

The new design has been submitted and approved by local council as part of a development application.

What will be the impact of construction on traffic flow?

Construction will be staged and traffic will be managed to reduce impacts on road users.

How will pedestrians and cyclists be catered for?

A shared cyclist and pedestrian path will be provided through the underpass on one side of Kennedy Drive and Holyman Avenue. Pedestrians will be able to use this path in both directions. Cyclists will be able to use this path travelling towards the airport.

7Major Development Plan

To build the new Hobart Airport Interchange, a section of Holyman Avenue will need to be realigned, as this is located on an area of the airport precinct that has been identified as Environmentally Significant in the Hobart Airport Master Plan. This triggered Section 89 of the Airports Act 1996 that requires a Major Development Plan (MDP) to be prepared for the realignment.

In April 2020, in accordance with section 94(2) of the Airports Act 1996, The Hon Michael McCormack MP approved the MDP.

Community consultation on the draft MDP  was undertaken in November 2019, in accordance with the Airports Act 1996.
