How can I find out more about the proposed expansion of Kooyong Road into a 6 lane highway?

Kooyong road is not being expanded. It was the Great Eastern highway that was expanded, and now finished. I live on Kooyong road, it was only widened a bit at the Eastgate shopping centre to meet the new intersection at Great Eastern Hwy.

The highway is nearly complete, just road marking and signage going in now. There are 3 lanes either side and the entry to side streets have been improved as well, some new traffic lights added. Paths on the side are almost complete and the centre median strip is being planted with new trees and looks pretty good as an entry to the city for plane/airport travellers. Has been a real headache with noise while they were doing work (often at night) and of course lane closures and traffic issues. I live nearby and hope to see and end to the project soon.

The lanes are being expanded where the Great Eastern Highway intersect with Kooyong Road.

This PDF from the MainRoads WA website show's the exact area that will be affected: http://www.mainroads.wa.gov.au/_layouts/getAsset.aspx?URI=3264410&REV=1&RCN=D11#163176
