New Lights, Witches' Hats

I never mentioned it before (I think) but there are new street lights up along the quay:

I think they're pretty, but I'm somewhat skeptical of how they'll hold up over time.

There are also a bunch of traffic cones along the walkway that have been there all week and I can't figure out why.

If you look, you can see they've even dug out the soil around them so they'll sit level.  Mysterious, no?
