Gauteng Braces for Major Road Closures During G20 Summit: Plan Your Routes Now to Avoid Delays
Johannesburg – As South Africa welcomes world leaders for the Group of Twenty (G20) Summit this weekend, traffic bosses are telling drivers and locals in Gauteng to map out their trips early. Big road blocks and slow-downs are on the cards from 18 to 23 November 2025, to keep things safe and smooth for the high-profile event.
A team-up of the Road Traffic Management Corporation, Gauteng Traffic Police, Johannesburg Metropolitan Police Department, Tshwane Metropolitan Police Department, Ekurhuleni Metropolitan Police Department and South African Police Service put out a joint note on the changes. They say these steps are key as the country hosts the big meet, pulling in top guests for the last talks under South Africa’s lead in 2025.
“These measures are necessary as South Africa proudly hosts the G20 Summit, a major international event bringing together global leaders. Motorists are encouraged to plan ahead, allow additional travel time, and consider alternative routes where 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.
“Clear signage, traffic officers, and real-time updates will be provided to guide road users, and access for emergency and essential services will be always prioritised,” law enforcement agencies said.
The blocks will hit spots in Johannesburg, Tshwane and Ekurhuleni, with rolling shuts when big groups move. This means full stops on roads for short times, up to an hour in some places, to let convoys pass safe.
Key Dates and Times for Closures
The main action kicks off on Saturday, 22 November 2025, and Sunday, 23 November 2025, with rolling blocks in the mornings from 07:00 to 10:00 and evenings from 17:00 to 20:00. But some roads close earlier, like the Golden Highway from Wednesday, 17 November 2025.
The G20 Social Summit runs from 18 to 20 November 2025 at the Birchwood Hotel and OR Tambo Conference Centre in Ekurhuleni, adding to the traffic mix in that area.
Prep work already happened, like a joint check on 15 November 2025, to test things out. All flights stay normal, but airport ways might see tweaks for smooth runs.
Major Roads and Areas Affected
The shuts focus on high-safety paths, including big highways and city main ways. Here’s a rundown:
- National and Regional Routes: N1 (Atterbury, Garsfontein, Delmas, Flying Saucer, Botha, John Vorster, Brakfontein, Samrand, Olifantsfontein, New Road, Allandale, Buccleuch, Winnie Mandela, Rivonia, 14th, Gordon, Maraisburg, N17, Rand Show), N3 south/north flyover, N12 (Elands, Voortrekker, Reading, Comaro, Kliprivier, Xavier, Uncle Charlie, Diepkloof), N14, R21 south (Atlas off-ramp, Voortrekker off-ramp), R24 west and N12 west junction, M1 (Woodmead, Marlboro, Grayston, Corlett, Athol Oaklands, Glenhove, 11th Avenue, Oxford, St Andrew, Jan Smuts, Empire, Smit, Carr, M2 Crown, Booysens, Xavier, Golden Highway).
- City and Arterial Roads: In Sandton (5th Street, Maude Street, Daisy Street, Rivonia Road, Grayston Drive, Katherine Street), Melrose Arch (Whiteley Road, Melrose Boulevard, Athol Oaklands Road), Rosebank/Westcliff/Parkview (Oxford Road, Glenhove Road, Jan Smuts Avenue), Fourways (Winnie Mandela Drive), Roodepoort (Hendrick Potgieter Road), Nasrec (Rand Show Road, Booysens Reserve Road, Nasrec Road, Golden Highway).
- Specific Full Closures: Grayston Drive shuts completely on Saturday, 22 November 2025, from 04:00 to 10:00. Golden Highway closes between Rand Show Road and Soweto Highway from 17 November. On 22 and 23 November, Nasrec Road blocks between Rand Show and Shaft 17 Road, with limited access from N17 circle to Shaft 17. Rand Show Road’s north part closes between N1 and Nasrec Road, while the south part turns two-way for Ormonde View locals. Booysens Reserve Road closes between Crownwood Road with limited access, and side streets like Amethyst/Crownwood and Modulus/Crownwood shut too.
In Ekurhuleni, routes like 1st Road, View Point Road, North Rand Road, Trichardt Road and Northern Road will see hits, especially around the Social Summit.
For the B20 Summit in Sandton from 18 to 21 November, Maude Street sees lane shuts to handle the crowd.
When convoys roll, roads close fully, stopping cars, walkers and bikes. They open soon after, but plan for 30 minutes to an hour waits in busy spots.
Alternative Routes to Beat the Traffic
To skip the mess, try these swaps:
- Use M57 instead of R21 between Ekurhuleni and Tshwane.
- For east-west trips, take smaller roads through Germiston, Kempton Park or Bedfordview over R24/N12.
- In Roodepoort, go Beyers Naudé Drive, Christiaan De Wet Road or Ontdekkers Road for Hendrick Potgieter Road.
- In Fourways, stick to Main Road, Cedar Road and Witkoppen Road.
- In Sandton/Rosebank/Parktown, use side paths like Corlett Drive, Sandton Drive or 11th Avenue for Jan Smuts, Oxford or Rivonia Road.
In south Johannesburg, Riverlea, Nasrec and Ormonde View, try Chris Hani Road, Main Reef Road, Crownwood Road, Soweto Highway, N17, Aerodrome Road and Adcock Ingram Road.
Clear signs, traffic cops and live updates will help guide you. Apps like Google Maps or Waze can show real-time changes too.
Why These Measures and What to Expect
The blocks are to boost safety, follow traffic laws and handle crowds during the summit. They tie into wider checks like car searches and flow control. Emergency teams and key services get priority access always.
South Africa takes the G20 lead this year, hosting the Leaders’ Summit on 22-23 November in Johannesburg. The event brings big chances for investment, jobs and tourism, but it means short-term pains for locals. Gauteng Premier Panyaza Lesufi has said the fixes, like better water and power, will last and help the area long-term.
If you must travel, leave early, use public rides like buses or trains, or work from home if you can. Stay tuned to radio, social media or city sites for updates. With good planning, the disruptions should pass smooth, letting the country shine on the world stage.
