If you notice one of the concepts has man made grass hills. It would be possible to put a grass hill in the middle and have cars going under it.
You could dig down maybe 1.5 meters, and have a grass hill maybe 2 meters high which would make it easily high enough for cars to go under and also means the hill wouldn't have to be ridiculously steep/high
Not sure if it would really fit aesthetically with how Victoria square is now. But still, it could work

What about buses? There's many bus routes that run through King William street/Vic square.
What about the tram? Is the tram going to run over the 2 meter hill? It's going to be a rather steep incline and decline for a tram in such a limited space. Or are you going to have the tram at ground level? That then present OHS issues for the general public and government.
At the end of the day what's stopping a tunnel is cost and the need to accommodate so many things.
They could do a tunnel under Vic Square(north-south), but then where would you put footpaths? Where would the trams go? How would east-west roads connect?
Not to mention the major disruptions it would cause to build it. Just remember the whining and moaning when they redid the northern section
