I did some motorway fixups on I-395 near the Pentagon and Arlington cemetary, based on aerial photos. There are definitely some complicated links there. I hope it got it right since I can see there has been recent construction in the area. Some was clearly poorer Tiger data, while other was hard to say. Somebody with local knowledge will have to sort out a lot of those links and lanes for directions and connections. What is that lane in the middle? I can't tell which way it goes. I wonder if it is a commuter lane that changes direction based on time of day... I'll leave that for someone who knows.
