Protesters barricaded Marlboro Drive in Sandton early on Monday morning over service delivery issues, Gauteng police said.
Lt-Col Katlego Mogale said a crowd blocked the road using rubbish and burning tyres from around 5am.
While it was believed the disruption was a service delivery protest, Mogale said it was not immediately clear with which services the community was dissatisfied.
By 9.30am no injuries had been reported and no arrests had been made, Mogale said.
Police were monitoring the situation. - Sapa
