Merimbula Airport will reopen on Friday, March 25.
Bega Valley Shire Council's project services manager, Daniel Djikic said the drier weather over the last week had enabled the works to progress.
"The final seal and line marking have been completed and the final safety checks undertaken to ensure we can safely re-open the runway on Friday," Mr Djikic said.
"We know the extended closure has been really inconvenient for the community, but we were at the mercy of the weather. By giving the runway those extra few days to dry out, we've been able to ensure the runway extension and resealing work is completed to a high standard and will last for years to come.
"There is still work to be done on the new general aviation precinct, as well as roadworks at the intersection with Arthur Kaine Drive, however the airport will re-open to travellers, airlines and general aviation users on Friday morning."
The council said the runway extension and strengthening project was an important step toward increasing the capacity and longevity of the airport, increasing tourism opportunities and making it easier for people to travel for business and leisure.
Council worked closely with the airlines and emergency services throughout the project and thanked the community for their patience.
The runway extension and strengthening project was funded through two grants from the Commonwealth government, two grants from the NSW government and a council contribution.
Traffic control will be in place on Arthur Kaine Drive throughout the remainder of the works as required.
