History

As of 13 December 2007, the D'Aguliar Highway bypasses Caboolture to the north. In January 2009, the Department of Transport and Main Roads published details of the preferred design for a bypass of the Kilcoy township. The proposed route follows an abandoned rail corridor, and would have minimal impact on existing infrastructure. In 2021, significant changes were made to the two main intersections in Kilcoy to improve traffic flow. This seems to have been done as an alternative to the proposed bypass. A project to provide wide centre lines near Wamuran, at a cost of $12 million, was completed in September 2022. A project to provide safety improvements between Sandy Creek and Kilcoy, at a cost of $19 million, was completed in mid 2023.
