As far as I understand, this bridge/roadway, and the precinct just to the west of it, is a part of the Polson/South River precinct and is a planned neighbourhood after the 2024 revitalization is complete, and the after the Villiers Island Precinct is underway. Nothing at this point is official on this bridge most likely, there could be no roadway there after all, but it is probably there to handle future density and traffic, just like how the Munitions Street Bridge is a future bridge that will be built over the Keating Channel after it is needed to serve the Keating Precinct and the Villiers Precinct. Anybody could add to this though, if they know any more information.
