THE new road crossing at Gerringong's Union Creek in Belinda Street has undergone a massive rethink, the new plans drawing widespread support.
NSW Roads and Maritime Services (RMS) have responded to community concerns about the original design.
Debra Moore, from the Concerned Citizens Group and the South Precinct committee, said the design, which was originally a culvert, would be upgraded to a short bridge.
"The changes will allow better passage under the bridge for our wide variety of migrating wading birds, including ducks, to cross under the road instead of over it, which would have meant they had to run the risk of being run over when crossing the road," she said.
"A lot of species of native fish and rare frogs [also] occupy the creek."
Mrs Moore said the community support was overwhelming, with more than 600 signing a petition in less than 18 hours.
Member for Kiama Gareth Ward said he was delighted with the outcome.
"The new bridge is narrower to provide more light and will . . . leave the creek bed in a more natural state, helping to improve the health of the creek.
"The upgraded bridge will also reduce localised flooding in Belinda Street."
Kiama councillor Andrew Sloan said he was grateful to the RMS for taking citizens' concerns seriously.
RMS project manager Adrian Rouse said planning could now proceed.
He said the impact of the closure of Belinda Street, the need to move existing utilities and the impact on local fauna needed to be considered.
"We will work through these problems and come up with a plan that will suit everyone," he said.
