Features and safety benefits of the project

The project delivered a safer and more efficient intersection through:

  • a grade separated interchange with Summerleas Road passing under the Huon Highway
  • roundabouts on Summerleas Road to provide safe turning movements
  • an overtaking lane on the Huon Highway for traffic travelling towards the Huon Valley (lane beginning immediately north of Kingston interchange)
  • a flexible safety barrier to separate traffic on the Huon Highway
  • facilities for cyclists and pedestrians
  • safer bus stop locations.


The Huon Highway is a key intra-regional corridor in Southern Tasmania connecting major industry sectors such as forestry, aquaculture and agriculture to central Hobart and other destinations.

Prior to these works, at the junction with Summerleas Road, the Highway passes adjacent to Kingston, one of Greater Hobart's highest growth residential areas. Summerleas Road is a major connection across the Highway linking residential areas to major commercial, educational and other facilities at Kingston.

The existing intersection had a history of crashes, notably those related to right-turn movements from Huon Highway to Summerleas Road and cross-highway traffic on Summerleas Road.


Work started in February 2017 and was completed in July 2018.


This project was funded by the Australian and Tasmanian Governments.
