Motorists travelling into Johannesburg this weekend are urged to prepare for significant traffic disruptions as world leaders arrive for the 2025 G20 Summit. With high-security convoys moving between OR Tambo, Pretoria, Sandton and the Nasrec summit venue, several major highways will face rolling closures, while parts of the Nasrec precinct will go into full lockdown. Authorities have warned that delays are expected throughout Saturday and Sunday, especially during peak convoy times.
The most affected stretch will be the N1 between Midrand, Centurion and Pretoria East, where a series of rolling roadblocks will intermittently shut sections of the highway. Key interchanges — including Atterbury, Garsfontein, Delmas Road, Botha Avenue, John Vorster, Brakfontein and Samrand — will experience stop-and-go restrictions as VIP convoys pass through. Motorists using this corridor are advised to either travel before 07:00, after 10:00, or expect extended delays during the morning and late-afternoon movement windows.
In Johannesburg’s south-west, the Nasrec / Johannesburg Expo Centre area will operate as a secure zone for the duration of the summit. Roads surrounding the venue, including Nasrec Road, Rand Show Road and nearby feeder routes, will have tight access control or hard closures. Anyone travelling near FNB Stadium, the M1 South or Crown Mines area should consider alternative routes, as traffic will be heavily diverted throughout the weekend.
Beyond the immediate summit precinct, several major Gauteng highways — including the N3, N12, R21 and N14 — have also been flagged for possible rolling closures as delegations move between key nodes. These restrictions won’t last the entire day, but motorists may encounter sudden stops, blue-light convoys and temporary block-offs. As a precaution, authorities recommend building extra travel time into weekend trips or opting for secondary roads where possible.
If you’re planning to travel through Gauteng, especially between Midrand, Centurion, Pretoria and the south-western parts of Johannesburg, prepare for slower traffic, intermittent closures and heightened security presence. With more than 40 countries represented at the G20 Summit, officials say disruptions are unavoidable — and anyone heading into Joburg this weekend should plan patiently and keep navigation apps close at hand.
