As Gauteng gears up to host the G20 Summit, motorists should brace for Saturday road closures and traffic alerts across key Johannesburg routes. On 15 November 2026, between 09h00 and 13h00, several high-traffic areas will experience temporary road closures, lane restrictions, and rolling lockdowns due to heightened security operations.

Coordinated by the Road Traffic Management Corporation (RTMC), Gauteng Traffic Police (GTP), Johannesburg Metropolitan Police Department (JMPD) and the South African Police Service (SAPS), this joint operation aims to ensure the safety of delegates, the public, and local infrastructure during the summit.

Why the Road Closures Are Happening

The G20 Leaders’ Summit is a major international event that brings together heads of state, finance ministers, and policymakers. With security as a top priority, temporary closures are necessary around venues and transport corridors in Johannesburg.

According to RTMC spokesperson Simon Zwane, “These operations are part of our broader security strategy to support a safe and well-organised G20 Summit.”
