Work is expected to begin in next financial year for a $1.26 million upgrade to the Wambianna Road between Warren and Dubbo.

The work will involve widening a part of the road by 2.5 metres, and installing barriers and installing signage indicating curves.

Warren Shire councillors voted on 26 February to fund the project in their 2025/26 budget with money from the Australian Government Black Spot (AGBS) program.

"There's a particular area where there's been a couple of accidents," Warren Mayor Greg Whiteley said.

"The next six months will be the planning phase.

"We encourage people to drive safely."

Wambianna Road recorded five road casualties between 2020 and 2024, according to Transport for NSW's online crash map.

Two incidents were on the same bend roughly 11 kilometres from Warren.

Four involved moderate injuries and one was serious.

The funding includes $100,000 for the design and investigation phase, with the rest set for construction beginning in the 2026/27 financial year.
