The Johannesburg Metropolitan Police Department JMPD says three legally approved marches are expected to cause significant traffic disruptions across the Johannesburg CBD, Hillbrow and parts of Midrand on Tuesday.
Thousands of demonstrators are expected to take part in separate marches focusing on community safety, illegal immigration and youth employment.
Motorists are being urged to expect road closures, rolling barricades and traffic delays between 7:00 am and 4:00 pm.
