Slums and pedestrian casualties

Two points here, this one, from the pages of Governing magazine, and this one, my comment on an Invisible Cyclist blog post.

You see this in the Bronx. The highway development there divides neighborhoods, creates unappealing choke points along crossings, generates excess noise and pollution, breaks up the grid to make it harder for traffic to flow smoothly around obstacles, streams extra cars onto city streets from off the highways, blocks access to waterfront areas, and alters mental geography to make relatively close-by places seem very distant.
