Great Eastern Highway Upgrade


New alignment being built to the south of the current highway, as well as a new intersection with Old Northam Road and reconstruction of Wooroloo Prison Farm access road.
Great Eastern Highway in Wooroloo

We are realigning a two kilometre section of Great Eastern Highway to improve safety and visibility. The new section is being built to the south of the current highway, on an alignment largely already cleared. It will include a painted median for separation of east and westbound traffic, as well as wider, sealed shoulders and safety barriers (where required).

We are also building a new intersection at Old Northam Road further to the south, and reconstructing the Wooroloo Prison Farm access road. Left and right turn pockets will be included at these intersections.

What's Happening

A construction contract has been awarded to Decmil. Clearing is complete, and construction of the side-track has started. Speed reductions to 60 km/h and temporary traffic signals are in operation.

The relocation of Water Corporation infrastructure and preparation of culvert areas is also progressing.


$11.5 million (80 per cent) Australian and $2.875 million (20 per cent) State Government.
