The roundabout at the intersection of Hallam North and Heatherton roads will be closed in all directions as part of works to build extra lanes and upgrade the area.
To improve safety and traffic flow, two through lanes and two right turn lanes will be added in each direction.
During the closure from 7am on Monday 3 January to 6pm on Sunday 30 January, 2022, the existing roundabout will be replaced with a smaller, temporary one to make progress on new traffic lights.
Barriers will be placed around the intersection to keep road users and workers safe during construction.
The route 842 bus stops at Heatherton and Reservoir roads will be closed throughout January, with the closest stop at the intersections of Tom Jones and Randle courts on Heatherton Road.
The route 863 bus stops at the corner of Hallam North Road and Thomas Mitchell Drive will also remain closed for the duration of the project.
The closest bus stops are at Belgrave-Hallam Road and the corner of John Fawkner Drive and Heatherton Road.
Locals will still be able to shops at Heatherton Village and fuel up at Shell Coles Express and United Petroleum.
A community information session will be held on Thursday 9 December from 4pm to 7pm at Heatherton Village for more information about the upcoming closure.
Members of the Road Projects Team will be available to answer questions.
