The project was funded through the Fixing Country Roads program to improve manoeuvrability of logging trucks in the area.

The total cost of the upgrades was $1.5 million with another $200,000 coming from industry funding and $50,000 from council.

Bathurst MP Paul Toole, who recently inspected the completed work with Oberon mayor Kathy Sajowitz, said the investment would significantly reduce costs to business and industry, while driving economic growth and improving the lives of people across the state.

"Economic growth in rural areas relies on agricultural commodities, industrial products and natural resources being able to move to market efficiently," Mr Toole said.
