It is not clear what sparked the blockade.
However‚ a community crime-watch group claimed on social media platforms that the blockade was related to foreign drivers.
On Sunday‚ traffic on the N3 highway between Pietermaritzburg and Durban came to a standstill following a blockade by aggrieved truckers.
It is understood that the blockade‚ which affected traffic in the Cliffdale area‚ was related to poor working conditions and the employment of foreigners by local trucking companies.
Transport minister Blade Nzimande called for the arrest of protesting truckers and the impounding of their vehicles.
