"We are making sure people are not moving in and around because of the rigidity and instability of the structures," Ntladi said.
"Together with the SAPS, EMPD and Prasa security we will make sure we keep this [scene] secured throughout the day up until everything is cleared up."
Police on Sunday arrested the 32-year-old driver.
The suspect faces multiple counts of culpable homicide and is expected to appear in court on Wednesday.
