Great Southern Highway improvements

Work to widen a 4.5 kilometre section of Great Southern Highway, in the Shire of Katanning, commenced on 10 December.

Works include:

  • widening 4.5 kilometres of highway between Strickland Street and McAuliffe Road, from 7.5 metres to 10 metres
  • reinstatement of sealed shoulders; and
  • installation of safety barriers and audible edge lines to address the risk of run-off road crashes at this location.

During preliminary clearing and site preparation works, traffic will be stopped intermittently and speeds reduced. 

From early January, road users will be detoured on to side tracks around the bridge works. Speed reductions will be in place and traffic will be reduced to a single shared lane (24 hour works). Access to Greenhills Road, Bushy Lane Road and Schultz Road will be maintained for local traffic only.

Great Southern Highway is a major link into the northern Wheatbelt, providing access to various tourist destinations, mining operations and pastoral communities. It’s also a key freight route facilitating a significant number of 36.5 metre road train freight movements.

Funded by the Federal and State Government ‘Regional Road Safety Program’, the works will improve safety and provide a greater level of service for heavy vehicle operation throughout the Great Southern Region.

We expect to be completed by March 2019.
