Gauteng MEC for education, Panyaza Lesufi, has officially opened a newly built walkway at the Hoёrskool Driehoek in Vanderbijlpark.
The MEC said more work had to be done to the school but it was officially declared safe.
A large cement walkway at the school caved in on 1 February.
Roydon Olckers, Jandré Steyn and Marli Currie died on the scene while Marnus Nagel later succumbed to his injuries in hospital.
Several others were injured.
The new bridge is a step forward for a school that's still healing.
But for some, this healing might only start once there are more answers about what exactly happened.
Three different investigations into the cause of the collapse have wrapped up.
The various teams now have 10 days to produce one consolidated report which will then be made public.
In the meantime, pupils are finally back in classrooms after spending months in temporary tents on the school's rugby field.
