How we maintain gravel roads

Gravel roads make up 420km of our road network. They need continual grading, drain clearing and the addition of gravel in order to stay in good condition.

Typically, our gravel roads were constructed many years ago as a result of the increasing demand from local farming and agriculture, and were not built with future traffic demands in mind.

There are a number of other factors that influence the overall performance of gravel roads: quantity and quality of gravel used in building the road, rainfall, drainage, quality of causeways and volume of heavy vehicle usage.
