The $2.6 million upgrade of Lord Baden Powell Drive is scheduled to get underway in September, weather permitting.
Council is preparing to go out to tender for the design and construction of works between Captain Cook Drive and MacLeay Street, as part of the Botanic Garden Precinct Renewal project.
The rehabilitation is expected to take 36 weeks to complete, depending on weather conditions.
The works will provide improved vehicle and pedestrian access to the Museum of the Riverina, Willans Hill Reserve and other locations along the road.
