Hi, Shaundrea, thank you for asking, this really is only half a roundabout, the former surface parking has moved underground, on the surface the second 'installment' of the park has recently opened, there is an extensive set on Mapillary, perhaps start the trail at https://www.mapillary.com/app/?pKey=1452789648825061 .
 
The 'watercolour' sketch at https://www.antwerpenmorgen.be/files/download/e88feb11-6128-403a-a353-61a26a964245 gives a decent impression, and there's a lot of information (in Dutch) at https://www.antwerpenmorgen.be/nl/projecten/gedempte-zuiderdokken/tijdlijn.
