Johannesburg - The Congress of South African Trade Unions (Cosatu) will stage a drive-slow protest against e-tolling in Ekurhuleni on Friday.
The Johannesburg High Court granted Cosatu an urgent interdict on Thursday allowing it to continue with the protest.
Cosatu went to court after the Ekurhuleni municipality and the police denied its request to protest.
Last Friday, a similar protest in Johannesburg had to be cancelled after the Johannesburg Magistrate's Court dismissed Cosatu's application to protest on the city's highways.
The Ekurhuleni protest would begin at Mbhoro Church, next to Huntersfield Stadium in Masakhane Street, at 7.30am on Friday.
Traffic on Heidelberg Road, the N3, N12, R24 and the R21 would be affected.
Last week, the National Council of Provinces passed the Transport and Related Matters Amendment Bill, paving the way for e-tolling to come into effect. - Sapa
