About this project
In December 2010 Roads and Maritime Services developed a preferred road corridor for the proposed realignment of the Princes Highway at Dignams Creek. The realignment of the highway was mostly to the east of the existing Princes Highway and would have required large scale bridge and road works.
This option for the road corridor was announced as the preferred option in 2010 and was initially estimated to cost $85 million. As the design was refined this cost estimate increased, mainly due to necessary increase in bridge length.
In light of increasing costs of the preferred option, Roads and Maritime reinvestigated other corridors. A new alignment to the west of the existing Dignams Creek Bridge was found to be better value for money. This alignment involved a reduction in the amount of earthworks and a shorter bridge. Initial investigations found it to cost around $40 million, about half the cost of the eastern alignment.
A Review of Environmental Factors (REF) for this project was completed for the alignment west of the existing Dignams Creek Bridge and was displayed for community comment from 27 June until 29 July 2013.
The REF for the western option was determined in 2013 and detailed design finalised in the first half of 2016.
The project has been allocated $15 million in the 2016/17 budget to start construction.
Plants and animals
The proposed alignment would result in disused sections of the existing Princes Highway being removed and revegetated. Wildlife corridors between Gulaga and Kooraban National Parks would also be maintained with substantial revegetation undertaken and fauna crossings installed as part of the road upgrade.
