N3 highway to remain closed for two days
Motorists have been warned.
A section of the N3 highway will likely remain closed for two days.
The SA National Roads Agency (Sanral) says an unused pedestrian bridge collapsed onto the highway last night.
The highway between the Van Buuren Road and the M2 Geldenhuys interchange has been closed.
Sanral spokesperson Vusi Mona says engineers are currently on site to determine the cause of the collapse.
Sanral says the pedestrian bridge was built in 1978 and has been closed off to the public for a number of years.
Residents in the south of Johannesburg have taken to social media with reports of the tremor which happened at around the same time as the bridge collapse.
However, officials are unable to confirm at this stage whether the collapse was caused by the reported tremor.
Motorists have been advised to avoid the area and to use alternative routes while the road is cleared and declared safe for use.
