A $2.2 billion Road Safety Package announced in the federal budget will enable Gunnedah Shire Council to apply for funding to improve "strategic roads".
Parkes MP Mark Coulton said this meant "extra money" for councils to draw on to improve "roads that are strategic for the region".
The MP said he had been in talks with the council about freight routes Clifton Road and Mystery Road, which have become the council's focus now that Grain Valley Road is in line for an upgrade.
Cr Chaffey said the roads had been identified as one of the "key corridors for transport" by the Namoi JO and was the council's "highest priority".
"We've worked with a consultant and identified right throughout five councils, strategic corridors that required improvements to make us more productive within our region," he said.
"It was important to understand traffic movement [and] when we look at the Mystery Road link with Clifton Road, it's a major corridor through Gunnedah and Liverpool Plains shire, mainly for cotton, so high volume traffic."
Cr Chaffey said Gunnedah council unsuccessfully applied for a Fixing Country Roads grant in late 2018 to fund the $12.4 million project.
"We'll be looking at feedback for reasons as to why we weren't successful and once federal funding opens again, we will be reapplying to see this crucial road corridor within our shire fixed or improved," he said.
The hope is to seal 13.4km at the southern end of Clifton Road and 8.3km of Mystery Road - 2.7km falls in the Liverpool Plains shire and 5.4km falls in the Gunnedah shire.
Cr Chaffey said Gunnedah was a winner in the 2019/2020 budget.
"[It] has identified a considerable amount for money of regional communities like Gunnedah and I'll be very interested to see what Labor's response to the coalition's budget is and of course the outcome from the upcoming election in May," he said.
"To have $66 million from Kevin Anderson is testament to our growing community and how we've been identified as a growing area for NSW and strategic importance for rural and regional NSW.
"Gunnedah is in a strong position [and] I'm sure once this crippling drought breaks, our primary producers will be able to get back to business as usual and will be back on track to continue to be an economic powerhouse for regional NSW."
