WATCH: Explosions and drilling to build new highway

THE Woolgoolga to Ballina project will upgrade about 155 kilometres of highway at a cost of $4.3 billion.

The project starts about six kilometres north of Woolgoolga and ends approximately six kilometres south of Ballina.

Where does the material come from to build such an huge project?

This video from Roads and Maritime Services answers that question.
