VicRoads will install new kerb and channelling on the Great Ocean Road, just east of Separation Creek, as part of its landslide remediation works.
The drainage work will be located above new retaining walls which were installed along the ocean side of the Great Ocean Road and completed in December last year.
The works will begin on Monday, April 3, and are scheduled for completion on April 28.
Traffic controllers will be in place between 7am and 4.30pm, Monday to Friday, during the construction period.
Works equipment and traffic management will be removed from the road during the Easter break when both lanes of the Great Ocean Road between Separation Creek and Wye River will be reopened.
