Northern Tablelands MP Adam Marshall announced on Friday $398,500 to upgrade the road over the next 12 months.

Glen Innes Severn Council will use the funding to widen the road and improve its alignment, Mr Marshall said, making it easier for drivers to see oncoming traffic and obstacles; install safety guardrails along the edge; and extend culverts along the road.

At least one fatal accident has taken place on Bald Nob Road in recent years: a woman was killed in a car crash in 2016.

The funding comes through the state government's Saving Lives on Country Roads Program, which aims to reduce the number of deaths and serious injuries on roads. According to Transport for NSW, drivers are four times more likely to die on a country road than in a metropolitan area.

"Bald Nob Road might only be 11.7 kilometres long, but it links the region's road network," Mr Marshall said.

"People travelling inland from the Queensland border to Grafton on the New England Highway can shave 30 minutes and 40 kilometres off their trip by taking Bald Nob Road at Dundee."

The Bald Nob upgrade is part of $22.5 million the NSW government has allocated to road safety projects in the Northern Tablelands in the 2019-20 financial year, Mr Marshall said.

From July, dangerous road shoulders will be widened and sealed, additional lines marked, and road barriers installed on the New England Highway, Thunderbolts Way, and Waterfall Way.

"We know living in country NSW often means a lot more time spent on our roads - and this program is about making those roads as safe as possible," Mr Marshall said.

"Every life matters, and that's why we're investing in life-saving measures across our road network to see that every motorist who sets off on a journey makes it home to their family and friends."
