In New Orleans sidewalk corners are adorned with delightful blue-and-white tiles, originally dating from the 1870s, telling you the name of the street you are crossing:
As I stepped over some of these, it occurred to met that they told a story about city planning.

These are designed for pedestrians, and perhaps bikers, using sidewalks. They reflect a time when planners were designing the city for people on foot.Lisa Wade, PhD is a professor at Occidental College.
