There are over 1,100km of roads in this area.
Repairs are prioritised using national guidelines. The cost of maintaining a road over its lifetime is expensive and treatments that provide the best long-term value will be considered first. It is often cheaper to treat a road before it deteriorates to the point where complete replacement is necessary.
Sometimes it will look like a ‘good’ road is being treated when we are addressing structural problems beneath. These problems are identified by radar surveys and the work maintains the condition of the road.
