Project update

Construction underway

Construction is now underway, with the first stage of works involving:

  • Demolition of the former BP service station site and other redundant buildings.
  • Site clearing of shoulders, median strips and other construction areas as required
  • Site investigations to identify the location of services and commencement of service relocations
  • The construction of a new access road to Cockman House
  • Temporary diversion of the shared path adjacent to Cockman House
  • Establishment of traffic management and site facilities

Community engagement

As part of the project, noise walls will be constructed in various locations to reduce traffic noise for local residents. Consultation is currently underway with local residents. See the Noise Wall Fact Sheet for more information.

There has been some interest in the community about the different design options considered when upgrading the intersection. An interchange Type Selection Fact Sheet has been developed to explain how the chosen option was decided.

A Community Reference Group has been formed to:

  • assist in identifying, discussing and providing advice on the community issues associated with the project
  • exchange information between us, the contractor and the community
  • provide representative community and stakeholder input into the construction phase of the project

The fourth meeting was held in April 2019.
