When it comes to G20 traffic, motorists in Johannesburg should prepare for significant disruption this weekend. The city will host delegates for the G20 Summit (22-23 Nov) and the B20 Conference in Sandton, prompting large-scale traffic operations. The Road Traffic Management Corporation (RTMC) has issued warnings of road closures, lane restrictions and rolling closures across major routes.
Why This Matters
The dry-run exercise scheduled for Saturday, 15 November 2025 (09:00-13:00) is part of preparations ahead of the G20 weekend. During this period, select national highways and urban arterials will be subject to “rolling road closures” where lanes are intermittently shut for motorcade movement and security checks. For commuters and local traffic, that means you should factor in extra travel time and consider alternative routes.
