An eyewitness - a taxi driver - says he saw the bus lose control on the highway:
The taxi driver mentions how he's dealing with what he saw:
Tweetpics have been coming in from 702Landers who have seen the bus hanging precariously from the Queen Elizabeth Bridge in the Joburg CBD. According to the JMPD, the driver escaped the incident without serious injury - he has been taken to hospital.
Speaking a few moments ago on the John Robbie Show, Metrobus MD Mavela Dlamini said the bus had just started it's route for the day so it was carrying no passengers. The driver allegedly lost control after leaving Ghandi Square and broke through the barrier. He has been taken to hospital.
Listen to Mavela Dlamini chatting to John Robbie...
