Member for New England, Barnaby Joyce, cut the ribbon on Tuesday on one of the last sections of Mount Lindesay Road, north of Tenterfield, to be upgraded from gravel to bitumen seal.
"This is yet another example of council working with the Federal Government to improve roads across the northern New England," Mr Joyce said.
"When the COVID-19 pandemic comes to an end - and it will - and the Queensland border wall comes down - and it will - better roads will see the return of even more tourists who'll provide a much-needed boost to our local economies like Urbenville, Woodenbong and Tenterfield."
The 3.5 kilometre section of road, at Wylie Creek near Liston, cost $860,000 and was funded through the Federal Government's Roads to Recovery (R2R) program.
Tenterfield Shire Council mayor Peter Petty said council had been focussing its efforts on sealing Mount Lindesay Road from Tenterfield to the Queensland border.
"Now that we have officially opened this section at Wylie Creek, there are only a few kilometres left to seal with bitumen," Cr Petty said.
Mr Joyce said the funding injection also made sure the earthmovers and their operators continued to work through the pandemic.
"This means local jobs have been maintained, driving wealth back into our local communities and the pockets of local suppliers."
