From a reader. (with regards to my post on Potomac Yard redevelopment)
You apparently missed the transit piece:

Here is the traffic improvement slated for Route 1, Alexandria.
The Crystal City/Potomac Yard corridor runs north-south between the Pentagon and Pentagon City in Arlington County and Braddock Road Metrorail Station in the City of Alexandria. The map at left shows the project location in a broader, regional context; and the map at right shows the system alignment divided into six segments. As indicated in the legend below, the purple lines represent portions of the alignment in which transit vehicles will operate in mixed traffic, while the orange lines represent portions in which transit vehicles will operate in an exclusive right-of-way. [via Crystal City/Potomac Yard corridor]
