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 was awarded to Decmil in mid-2021 and work started in August 2021.

Traffic has now been redirected onto a temporary alignment between the Acacia Prison access road and Old Northam Road. This will allow us to complete earthworks for the southern tie-in to the new section of highway. The speed is reduced to 60 km/h throughout the worksite and temporary traffic signals are occasionally in operation.

Water Corporation infrastructure has been relocated and preparation of culvert areas is progressing.


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