DEADMANS Creek Rd, which leads into Ballina Heights, will remain open following a decision at the last council meeting.
However the road could be turned into a one-way street with a weight limit.
The road regularly floods, and its height also has major flooding impacts on upstream properties.
Nearby residents have also complained about the noise caused by construction trucks using the road to access building sites at Cumbalum.
But closing the road would have considerable "social and economic costs" to more than 250 residents.
Also, with Ballina Heights Dr now open to traffic, Deadmans Creek Rd is no longer the only access point to the area.
Ballina Shire Council's acting general manager, John Truman, said the council had decided to lower the road.
It will cost about $250,000, and the council has voted to apply for flood assistance grants to help pay for the project.
Mr Truman said councillors also requested another report to consider making Deadmans Creek Rd one-way, and to impose weight limits.
