This major hospital could do with some tender loving mapping; access was initially and provisionally, mapped when the Stuivenberg A&E was transferred early. 

Visited the area 14 sep'24, taken additional pictures, please also refer to https://www.zas.be/locaties/zas-cadix and https://www.zas.be/locaties/zas-cadix#bereikbaarheid ;

For example indicating the four ground level entrances - in addition to the two ramps down to the lower levels : one for emergency vehicles and general deliveries, the other for cyclists, kidney dialysis and visitors / out-patients. 

As to access via this crossing : why on earth would one like to go up steps, wait quite a while for a green pedestrian light, walk down steps - there is a ground level passageway just to the east which brings you near the A&E / visitors entrance w/o the steps and wait for traffic lights.
