The work compound has been taken away and the former speed zones are in play once again.
The upgrade of Mullumbimby Road is 99 percent finished.
The only remaining work to be done is a final seal which will happen later in the year.
"I know Council is certainly pleased to see this project all but finished and without hesitation I can say that the community is too," Phil Holloway, Director Infrastructure Services, said.
"The upgrade of Mullumbimby Road was a challenging project, primarily because of the amount of traffic that uses the road on a daily basis," Mr Holloway said.
"Mullumbimby Road is the second busiest road in the Byron Shire and any work on the road is a major disruption to drivers.
"On behalf of Council I thank the community, businesses and everyone who was inconvenienced by the project, for their patience and understanding," he said.
"The upgrade of the road means it is now more resilient to nuisance and flash flooding," Mr Holloway said.
The upgrade of Mullumbimby Road was a major project funded by the NSW and Federal Governments, and Council, to improve road safety and drainage and rebuild flood-damaged sections of the road.
