Across the course of five months, work will see the road's shoulders widen, with the surface receiving a facelift too.

The NSW Government has provided $2.4 million for this road safety upgrade.

Bathurst MP and Minister of Regional Transport and Roads, Paul Toole, said the section of road - which is roughly three kilometres north of Bathurst - was earmarked for improvement because its small road shoulders made it difficult for vehicles to recover if they veered off the road.

"We are working to improve the safety of motorists by widening and sealing the road shoulders, replacing the current road surface and improving drainage," Mr Toole said.

"We're also thinking long term by strengthening and overlaying the road surface, which will provide up to a 20-year design life and reduce the need for ongoing maintenance."

Mr Toole said the project is one of many across the state being rolled out.

"This is about getting money out the door and into our regional and rural areas to improve our roads," he said.

"We know that when people in the country get behind the wheel of a car, they have to travel longer distances. So it's important for them to have safe roads for them to drive on.

"Through our Safer Road Programs, we've got $822 million that is being rolled out and we've just announced another $252 million for another 384 projects and they are in regional and rural parts of NSW.

"In the local area there's many projects that are going to beneficiaries of this funding and investment.

"It's critical to have safe roads and that's why we're going to continue investing in the bush."

The road caters for up to 500 motorists a day and up to 3500 motorists a week, connecting Bathurst will surrounding villages of Sofala and Wattle Flat, while also providing a route to Mudgee.

Bathurst mayor Bobby Bourke said the work is long overdue.

"The work has been needed out here for a while," he said.

"It's not too bad and there has been improvements in the past. This money will go a long way to improve this area of road."

Work will be carried out between 7am and 5pm on weekdays and a 40 kilometre perhour speed limit will be in place during work hours for the safety of motorists and workers.

Work is expected to be completed by the end of September, weather permitting.
