Commuters are being advised they can expect days of up to 15 minutes as works along Napier Street continue today.
Single lane closures will see the traffic slow, as crews continue with line marking and tree planting between Scott Street and Orville Way.
Speeds will be reduced to 40km/hr and traffic monitors will be on site to guide traffic through the worksite.
The Napier Street upgrade began in July 2017 and is estimated to take two years to complete.
More information about the detours and project can be found on Regional Roads Victoria's website.
