Traders at the Early Morning Market in Warwick Junction have refused to move to an alternative site.
The traders, who occupied the Early Morning Market for more than 90 years, are refusing to make way for a shopping mall and have threatened to bring Durban to a standstill next week.
Retrenched Remant Alton bus drivers, who have not been taken on by the city's new bus service operator, are expected to join the protest marches.
More than 26 trader organisations have signed on to the city's development plans, but organisations representing the market traders have vowed that they will not move from their historic site in the city centre.
Gaby Bikombo of the World Class Cities for All campaign said they would meet next Wednesday to discuss a way forward.
Traders walked out of a meeting at the Durban City Hall last week after city manager Mike Sutcliffe announced a new plan for the mall.
The traders are waiting for a ruling on their court application not to moved. Developers cannot resume construction until the ruling is handed down.
