During the 2009 upgrade of the Widden Creek Bridge, an Aboriginal cultural site was discovered within the work zone. To safeguard the area and its cultural significance, an Aboriginal Heritage Impact Permit was obtained and archaeological works were undertaken in accordance with NSW Office of Environment and Heritage guidelines.

The salvage program, carried out in four phases, involved collecting artefacts from the surface, excavation pits, spoil heaps, and an undisturbed soil pedestal. Approximately 3,000 stone artefacts and fragments were recovered. Most were crafted from locally sourced mudstone, with smaller numbers made from chert, quartz, tuff, basalt, chalcedony, siltstone, and petrified wood.

A specially selected group of 128 artefacts now forms the Widden Creek Bridge Aboriginal Artefacts Display—a vision brought to life by respected community Elder Aunty Margaret Matthews. Her aspiration was to ensure this cultural knowledge continues to be shared, honouring both the long history and living presence of Aboriginal people in the region.

This display is more than a collection of tools and fragments—it is a powerful reminder of enduring connection to Country and culture. It can be viewed at the Muswellbrook Council Administration Centre, 60–82 Bridge Street, Muswellbrook. Visitors are encouraged to explore this important display and reflect on the depth of local Aboriginal heritage.
