I've noticed that in the past week Google has added much more traffic detail to its maps not only for the DC area, but for most of the largest cities in the US.Every day I check back to Google Maps another neighborhood has been added to the live traffic feed. It looked like Dupont Circle was the first non-highway region inside of DC to be tracked for traffic.
In terms of Clarendon, now Route 50 and Lee Highway have live traffic feeds! Hoping they add Washington Blvd next.
