Melton council is duplicating Hume Drive between Gourlay Road and Calder Park Drive by increasing the existing two lanes to four lanes with a new road median.
The council said the current single lane carriageway is congested at peak times and the road duplication will improve the flow of traffic along Hume Drive, making it safer for all road users.
The project is valued at $8.8 million and construction commenced in December.
The council said it is to keep the road open to traffic during the works, but there may be periods of time where there are reduced lanes and delays occur. 40km/h speed limits will be in place throughout the works.
Road users are advised to allow extra travel time and to use alternative routes if possible.
Traffic disruptions will be communicated ahead of time through electronic sign boards to help drivers plan ahead.
As part of the road realignment and duplication council will remove trees and shrubs, which will be re-landscaped with new plants and trees once the intersection upgrade is complete.
Access to the Taylors Hill Village Shopping Centre will be maintained throughout the works.
During late 2024, works will be required near to the Taylors Hill Village Shopping Centre that will impact the way vehicles enter and exit the shopping centre car park.
The council said it will provide an update ahead of these works and signage will be in place advising of traffic changes.
