Mr Kilby, who has three properties along the Narromine-Eumungerie road, said it only took five days for a hole to develop into a pothole nine foot long and five foot wide, and almost six inches deep.

He said while the councils responsible were patching the road, it wasn't suitable for the amount of traffic using it.

"[The hole] would be like you ran up to the footpath with your car off the street, that's how bad the hole was," Mr Kilby said.

"What they're doing is not suitable, it's not fixing the road for all those trucks. The new work that they're doing the trucks are wrecking it already.

"The consolidation under the tar there is awful, it's loose, sandy and little rocky dirt. I've got the dirt that's there and you could go and make sandcastles with it. And this is supposed to be holding the tar up so the trucks can drive on it."

The Narromine Shire Council, responsible for the Tomingley to Narromine portion, said they were aware work needed to be done to develop the road to a higher standard.

Narromine Shire general manager Jane Redden said that the upgrading of the road had been the subject of joint funding applications from the Narromine, Gilgandra and Dubbo councils who each have responsibility for portions of the road, but said it was not within their council's road budget to complete.

"Narromine Shire Council spends a significant proportion of its local roads budget on this road and is actively lobbying for additional funds for its repair and upgrade," Ms Redden said.

"The upgrade to a higher standard will take significant resources and is beyond council's roads budget."

Mr Kilby said in only 17 minutes he witnessed 27 trucks using the Newell Highway and Narromine road and said the councils responsible should be looking at it more seriously.

"The Narromine road to Eumungerie is not safe for traffic. It's not built or constructed right, in five days you've got a pothole that big that someone can blow a tyre and run off into a tree," he said.

"The shire have to go along every second day and patch up the road, or they have to re-build the road."

A spokesperson from Dubbo Regional Council said they are aware of a number of pavement defects that are scheduled for repair.

"Dubbo Regional Council maintain only around 19km of the 92km route, the northern end of Eumungerie Rd between Collie Rd and the Newell Hwy," the spokesperson said.

"In recent years the council has undertaken pavement widening works on Eumungerie Road and routine maintenance works are regularly undertaken.

"Heavy patching is currently being considered for inclusion in the 2019/20 works program, however no further significant upgrades are currently planned for that stretch of road that DRC maintains."
