I think it's just the traffic lights right now. I haven't seen or heard of any crossing guards. I don't think many, if any, people are actually walking it out, and there should be even less as it starts to get hotter out.
BTW, is there a known deadline for the pedestrian bridge and path to be completed? I'm guessing it should be around the time the second phase of Cabana opens, but is there a date like there was with the TM parking garage? :shrug:
