Gladstone Regional Council has thrown its support behind a local inventor who has developed a floating boom gate.
Miriam Vale man David Bagnall came up with the idea to attach a floating boom to both sides of the road, so the gate automatically closes when a road is flooded over.
Mayor Gail Sellers says the council has allocated $40,000 to install two prototype units within the region.
"It's one of those wonderful stories of a small operator who saw a need and then filled the need by inventing his own floodgates," she said.
"David is a truck driver and he saw the dangerous situation on those gravel roads and on bitumen roads and felt that he needed to be able to help."
