The SE quadrant is separated from the other three quadrants with double barriers, first a river and then freeways (DC-295 and Interstate-295); one could easily forget it is DC too. On my first drive in some of the neighborhoods there, I came to recognize instantly the differences between the two sides and the significance of these physical barriers. Indeed, all the freeways in the city, legacies of the past, have proved to be a bad idea. If you’d walked in town, you would understand the frustration of crossing them and those bridges around them. They block the flow of everything and cause segregated development patterns.
