I wonder, if there were no small ridges, how the water would behave during rain. Do the small ridges break it up so that it's not a complete sheet of easy-to-slip-on-it water? (or ice) (well, I don't know that Phoenix has that much ice) IANAA (I am not an architect)

The ridges would give better grip when wet, but the bridge would get covered in ice much easier

Phoenix is the name of the bridge, not where it has been installed. Also not an architect, but I suspect this wouldn't get installed in Phoenix as shown, I don't think it meets US ADA accessibility requirements: the slope looks a bit high, there's no level landing at the top, and the concave surface of the ramp seems problematic as well.

  Provided there are enough other crossings of those paths, does it have to meet ADA requirements? It's not really providing any function besides connecting paths, and if the same function is also provided a stone's throw away this structure isn't a big bother. Not that we should dot our landscape with such things

    For new construction, the standard is roughly "In new construction, all areas must be fully accessible, including multiple spaces of the same type, unless otherwise specified." [1] I don't think a useless bridge on a roughly flat site (as depicted in the installation images) qualifies for exceptions, IMHO. There's no reason it would be impractical to make it accessible, so it must be made accessible.

      Does this mean that you can't put stairs next to a ramp or an elevator, because the stairs aren't accessible to people with wheelchair?

        I don't think ADA guidelines prevent installing stairs with ramps, and egress requirements may require stairs with elevators.
