Safety on Paynes Crossing Road between Cessnock and Singleton has been upgraded with a $2.44 million dual-lane bridge.
The replacement bridge, almost 12 kilometres north of Wollombi, has an improved alignment and is three metres higher than the old deck.
Regional Transport and Roads minister Paul Toole, who visited the bridge on Monday, said the new structure had an open weight limit.
"The old bridge had a six-tonne load limit in place, meaning fire tankers filled with water weren't able to use it. This new bridge has an open load limit, providing fire crews more reliable and safe access to local communities in times of need and natural disaster," he said.
"It's also going to allow for a more reliable movement of freight."
Construction of the bridge supported 20 local jobs.
Cessnock City Mayor Councillor Bob Pynsent said the project was a win for locals and tourists.
"As a result of us working together with our neighbours we've provided the community with vital new infrastructure that better serves their needs," he said.
"The new bridge is three metres higher than the old structure, has two lanes, a longer life span, and the improved alignment makes it safer for drivers. It will benefit locals and visitors who frequent the area."
Singleton Mayor Councillor Sue Moore said the structure's higher load limit is also of considerable benefit.
"The old bridge was load limited restricting the movement of freight in this area. Importantly, the new bridge means the local RFS tankers can now cross the bridge and provide adequate protection to locals, which is fantastic news," she said.
The Federal Government provided $667,000 from its Bridges Renewal Program, the NSW Government contributed $668,300 from the Fixing Country Roads Program, and the Cessnock and Singleton Councils contributed the remainder.
Deputy Prime Minister and Minister for Infrastructure, Transport Michael McCormack said the project was an great example of all three tiers of government working together.
"The new dual-lane bridge will not only provide a safer crossing for transporters of livestock and other agricultural products, but will also reduce councils' maintenance costs as it won't require the same level of upkeep as the 72-year old bridge."
