From Monday 9 November, RRV will asphalt 14 kilometres of key sections between Waurn Ponds and Little River.
This includes eleven sections of Colac-bound lanes between Little River and Draytons Road, and five Melbourne-bound lanes between the Hamilton Highway overpass and Beach Road off-ramp.
Lane closures and reduced speed limits will be in place, however every effort will be made to limit the disruption for drivers.
These measures include rolling out the works at night from 8.30pm to 5am from Sundays to Thursdays, reopening lanes during the day and pausing works during the peak tourist season from Friday, 18 December to Sunday, 31 January.
These upgrades follow nearly 30 kilometres of improvements delivered along the Princes Freeway over the past two maintenance seasons.
