Residents in Wedderburn no longer need to fear heavy rain isolating them from the rest of the community.
The new Wedderburn Bridge was officially unveiled last week.
The bridge will allow residents to enter and exit their small suburb during times of heavy rain, when in previous years they would have been stranded by flooding.
The two-lane bridge project - which Wedderburn residents had long campaigned for - was jointly funded by the federal government and Campbelltown Council.
Western Sydney senator Marise Payne joined mayor George Brticevic to unveil the bridge last week.
"When I visited the site in December 2018, works were in progress but today I am pleased to see the bridge complete and providing safe and reliable roads for the local community," Senator Payne said. "This is a prime example of [investment] in grassroots infrastructure projects in western Sydney."
