Preliminary investigations suggest an earth tremor caused by mining activity in the early hours of Wednesday may have caused the N3 bridge collapse.
Five people were injured on the N3 highway in Germiston near the Geldenhuys Interchange.
Two people injured in the collapse have now been discharged from hospital while a third person remains in a critical condition.
