The N3 highway reopened for traffic on Thursday after a pedestrian bridge in Germiston collapsed in the early hours of Wednesday morning.
The stretch between Van Buuren Road and the M2 Geldenhuys interchange was closed for several hours.
Four people were injured in the incident. The pedestrian bridge was lying across the highway in both directions. Three trucks and a Mercedes-Benz sedan crashed into the bridge
The road has now been declared safe after engineers spent the night removing the debris.
The cause of the collapse is still unclear at the stage.
A pile of rubble next to the highway is the only evidence of the collapsed bridge.
It’s understood the bridge was built in 1978 and was regularly inspected.
During the latest inspection last July, the bridge was declared safe.
At the time of the collapse, the bridge was not in use.
Meanwhile, the City of Ekurhuleni says its appointed a committee that will look at all other bridges in the area to ensure safety. The city’s MMC for infrastructure Robert Mashego said: “We have created a committee to look into that.”
