Or maybe start thinking in three dimensions. The subway is already the first step in that third dimension. Why not add more layers (either up or down) ?

  I wonder what the costs are of the plan in the article and how it compares to digging more tunnels for subway (down) or adding some kind of elevated rail (up).

    That would've been a good starting point for them for sure. A cost benefit analysis would probably be too much to ask for, but would at least make it less of an opinion-type piece. I actually had the thought that streets should not be for people - put people up on skywalks (indoors or outdoors), and reduce the amount of people on the ground. Could also make for a much nicer experience for the people as well. Doesn't seem like it would cost a ton to just do that.
