Collie Lake King, Gibbs Siding

Collie Lake King Road is a heavy haulage route, currently carrying freight trucks up to 36.5 m in length and weighing up to 107.5 t. It also serves as a tourist and inter-town route.

In October 2014, Former Minister for Transport Dean Nalder announced improvements to the Collie Lake King Road including works at Gibbs Siding to improve freight connections from the area to the Port of Bunbury, benefiting local producers and allowing grain exports horizontal and vertical alignment. 

The project involved the realignment of a 4 km curved section of the existing road, located 6 km west of Darkan in the Shire of West Arthur. 

Following a public tender process, the contract was awarded to Maca.

Construction commenced in November 2015 and was completed in May 2016. Pre-construction site works, including vegetation clearing, were completed in late 2015. 


Environment and heritage

Extensive environmental investigation and consultation with local community groups and government agencies took place throughout the project.  This included consultation with traditional owners who determined that there were no Aboriginal heritage issues.  Some clearing of native vegetation was necessary, however none of the affected vegetation was considered threatened or declared as rare or priority flora.
