We’ve progressively completed reconstruction, widening and road repairs on numerous sections of the Highway. Intersection improvements are also complete, along with replacement of the Hotham River Bridge.
- Widening the highway and installing safety barriers between Kojonup and Balgarup Road.
- Intersection improvements at Crossman Road and Crossman Dwarda Road, which includes widening lanes and shoulders, new right turning lane into Crossman and Crossman Dwarda roads, a new left turning lane into Crossman Dwarda Road, and upgrades to the southbound rest area.
- Reconstructing and widening a 5.7 km section between Gordon River Bridge and Pinjalup Creek Bridge, and new safety barriers at Frankland Cranbrook Road and Rockwell Road.
- Road repairs to 13.5 km of highway between Jarrahdale Road and Williams, across 5 sections.
Gordon River Bridge in the Shire of Cranbrook
An extensive environmental impact assessment has been undertaken, including completion of three biological surveys to assess the potential impact on Threatened Ecological Communities (TEC) and the required clearing of native vegetation on this section of the project.
A biological survey completed in October 2018 located flora species acacia prismifolia previously thought to be extinct, within the road reserve. It has since been established that there are approximately 1500 individual plants in both the road reserve and adjacent private property.
To lessen the impact to this rare species, the project design and scope was altered to shorten the length of horizontal and vertical curves, designing steeper embankments and installing kerbing and safety barriers to minimise impacts to the acacia prismifolia population.
