As nice as the renderings are, there is still a major problem with Hart Plaza that is not addressed that will prevent it from being an integral part of downtown... the vast, imposing stretch of concrete that acts as a moat. We call it Jefferson Ave. You want to have a nice park/plaza that connects downtown to the river? Do something about the 10 lane freeway on/off ramp that acts nearly as much as a border as the river to the south.
