Old Bar residents and visitors are being asked to use extra caution when travelling in the vicinity of Saltwater Road and Forest Lane.
MidCoast Council crews will start roadworks in the area on Monday 14 August.
The works include reconstruction and sealing of Forest Lane and road widening along the intersection of Saltwater Road.
Work is expected to take three months to complete weather permitting.
The roadworks come after crews performed tree clearing work last month in preparation for the project.
Council's Director of Infrastructure and Engineering Services Rob Scott said that particular section of road was a main connector route for many residents.
"The improvements are essential to cater for future development in the area. The project has also been high on the community's agenda for several years " he said.
"This work will improve safety and efficiency for road users and is part of our focus on improving local and regional roads on the MidCoast."
The project is being part funded through Round 3 of the NSW Government's Accelerated Infrastructure Fund.
