In mid-January, works will begin to widen and resurface a section of Cape Otway Road in Modewarre, between Taylors Road and Church Road.
These works will improve road safety and help ensure Cape Otway Road can cater for current and future traffic volumes.
Surf Coast Shire Councillor Adrian Schonfelder said the widening and resurfacing works would make a big difference, and followed recent upgrades to other sections of Cape Otway Road.
"Council's Road Network Management Plan identified Cape Otway Road as the highest priority local road in the shire for rehabilitation and widening, with a particular focus on the section between Moriac and Buckley Road South," he said.
"Lane and road closures are necessary during the works, but we are doing all we can to minimise the impact on drivers, including opening the road at nights and weekends during the main works."
From 18 January, for approximately two weeks:
Lane closures will be in place on Colac Otway Road, between Hendy Main Road and Layards Road.
Vehicles will still be able to get through, but there may be delays.
From 1 February, for approximately six to eight weeks:
Cape Otway Road will be fully closed to traffic from Hendy Main Road to Layards Road on weekdays between 7am and 5pm, with a detour in place.
Cape Otway Road will reopen to traffic outside of these hours and on weekends.
People living on this section of road will be able to access their property at all times but may experience some minor delays.
Emergency vehicles and school buses will be permitted through the road closure.
Signage and traffic management will be in place during the works, and there will be reduced speed limits for a longer period.
The project has been funded by the Federal Government's Black Spot Program.
