Crappy Crossings" of Columbia Heights, aka the worst intersections. At the time, 14th and Park won and several commenters agreed.
But now... with the pitiful two-lane road and mass of construction to fuel our new fountain... is there anything worse than 14th and Irving? It's perpetually blocked by buses and backed up traffic. Pedestrians have to weave through traffic to find a way through, no matter which corner they leave from. And the drivers are angrier than ever.
The only upside: our fountain is looking lovely and more of that construction seems to wrap up on a daily basis.
