Simon Cozens, captain of the Woolsthorpe brigade, said the Heywood-Woolsthorpe Road was becoming increasingly dangerous.

He said it was now a popular route for trucks and recent repairs of a large pothole were already failing. "It's already breaking up and I'll be the one who has to go out when someone has an accident," Mr Cozens said.

Member for South West Coast Roma Britnell said she was deeply worried about what would happen if someone hits the pothole at speed.

"This is yet another disgraceful example of Daniel Andrews and Labor ignoring country Victoria," Ms Britnell said. "The pothole has been reported many times, but the answer is to stick up a warning sign, lower the speed and throw a bit of bitumen mixture on it."

Ms Britnell said she believed the state government was unprepared to deal with increased number of trucks using the road, despite approving wind farm permits.

Regional Roads Victoria's south-west regional director Emma Miller-Olsen said some interim repairs to the stretch of road had been completed. She said the road was being monitored and a plan for a longer-term solution was being developed.

"Making sure our roads are safe for the community is our first priority, which is why we continuously roll out road improvement projects and undertake regular safety inspections right across the network," Ms Miller-Olsen said.
