Johannesburg - Gauteng saw two protest actions in Olievenhoutbosch in Centurion and in Soweto as residents protested and blocked roads on Tuesday, Gauteng traffic police said.
"Burning tyres, stones and rubble are being used by protesters to block the roads."
"Motorists are advised to avoid Olievenhoutbosch and Kliptown due to protest action," said spokesperson Obed Sibasa.
The R55 was closed to traffic between Centurion and Kyalami.
Sibasa advised road users to use the N1, the old Johannesburg Road or N14.
Police monitoring protests
Earlier, police spokesperson Lieutenant Colonel Lungelo Dlamini said it was not yet clear why Olivienhoutbosch residents were protesting when they started gathering on the road and blocked the route.
"They did not use anything to block the road, they just gathered in the middle of the road."
"Police are monitoring the protest, so far no violence was reported."
Further afield, protesting residents in Kliptown, Soweto blocked the Union Road.
The road between Pimville Golf Course and the Kliptown Flats has also been closed, Sibasa said.
"Motorists are advised to use Klipspruit Valley Road from Chris Hani Road, and if travelling from Eldorado use the N1/N12 or the Golden Highway," he said.
