I am a big, big fan of maps. The advantage of this map is that it is very useful for planning purposes. The primary drawback to this and many other maps is that the veracity of the source is generally not verifiable. In this case however, I was able to confirm that some of the "probably closed" roads were in fact, impassable. How could I do that? It turns out that latest update to google imagery was also about that same time. And the resolution of the imagery was good enough to show that a collapsed building had completely obstructed the road.
