Protesters set alight tyres on Macassar Road resulting in road closures.
The N2 incoming, from Macassar to the R300, was closed and traffic was diverted.
Roads were filled with burning tyres and rubble.
Cops were then called to Mew Way where a five-car pile-up involving a truck left one person dead and two hurt.
Authorities are yet to disclose whether the misty weather or burning shrubs set alight by protesters was the cause of the accident.
