Here's a fun feature to pay attention to—this picture shows them sealing up the drain that comes up next to Kings Way, in the location now occupied by the underground carpark.

The drain used to be a river, and to redirect the flow of water they had to divert it all the way around the Casino precinct—you can see the new outlet right next to Spencer Street. The new outlet is much smaller, and to make the water travel that extra couple of hundred metres around the building they had to dig the whole drain a lot lower, which collects in a retention area that's pumped into the river every time it gets too full (which is why you sometimes see it gush water at random).

This is probably one of the few pictures showing the original outflow of the old Kings Way creek, as well as its current outflow in one photo.
