- There will be major road closures across Gauteng this weekend to accommodate the G20 Summit in Johannesburg.
- Motorists are advised to use alternative routes, allow extra travel time, and follow real-time traffic updates as closures may last up to an hour in some areas.
- The closures have already affected Friday commuters, delaying matric exams and flights ahead of the summit.
Gauteng motorists have been warned about road closures on Saturday and Sunday to accommodate the G20 Summit.
A joint operation between the Road Traffic Management Corporation (RTMC), Gauteng Traffic Police (GTP), Johannesburg Metropolitan Police Department (JMPD), Tshwane Metropolitan Police Department (TMPD), Ekurhuleni Metropolitan Police Department (EMPD) and South African Police Service (SAPS) will result in temporary road closures, lane restrictions, and intermittent disruptions across key routes.
According to the RTMC, the closures will affect the major metros like Johannesburg, Tshwane and Ekurhuleni in the form of rolling roadblocks.

Despite having set times, closures will also be implemented as and when convoys are moving.
“When the convoys are moving, roads will be closed off completely and movement from road users, pedestrians, cyclists, and motorists will be limited. Roads will be opened as soon as the convoys move past the affected routes, with approximately 30 minutes to one hour delay in some areas,” the RTMC said in a statement.
The following major closures will be implemented:
- Saturday – A full closure on Grayston Drive will be implemented between 04:00 and 10:00.

The RTMC advised motorists to plan, allow extra travel time, and consider alternative routes if possible.
“These measures are essential to enhance public safety, enforce traffic compliance, and support ongoing traffic law enforcement initiatives, including vehicle inspections and congestion management,” it said.
“Clear signage, traffic officers, and real-time updates will be provided to guide road users, and access for emergency and essential services will always be prioritised.”
Motorists are advised to take the following alternative routes around Johannesburg, Ekurhuleni and Tshwane:
- Use M57 as an alternative to the R21 between Ekurhuleni and Tshwane.
- For east-west travel, use smaller regional roads through Germiston, Kempton Park, or Bedfordview instead of R24/N12.
- In the Roodepoort area, use Beyers Naudé Drive, Christiaan De Wet Road, and Ontdekkers Road instead of Hendrick Potgieter Road.
- Within Fourways, use Main Road, Cedar Road and Witkoppen Road.
- Within Sandton/Rosebank/Parktown, use side streets parallel to Jan Smuts, Oxford, or Rivonia Road, such as Corlett Drive, Sandton Drive, and 11th Avenue.
- In southern Johannesburg, Riverlea, Nasrec and Ormonde View, use Chris Hani Road, Main Reef Road, Crownwood Road (Fordsburg–Crown Mines), Soweto Highway, N17, Aerodrome Road and Adcock Ingram Road.
