Tuesdays my dog and I usually walk in and out of the city via the Williamsburg bridge. Today the bridge is covered in snow, so instead here's a picture. Technically it's a NYC Greenway, but as you can see it's more like a Grayway.
I want to get Michael Bloomberg (or Reverend Billy if he winds up being the mayor) to help me (us, really) get the whole thing planted as a vertical garden. Here are some examples from France and Japan:
Simply covering the bridge in sedum and moss would make it a delightful thing to walk over in the summertime, do a lot to mitigate urban heat island effect, look beautiful from far away, and turn our ugliest of the five bridges into a huge statement of NYC's seriousness about sustainability. It's practically shovel-ready!
Here's more information about architectural vertical gardening.
