Imagine A Train on the Shirley Highway

Yesterday i discussed the possibility of putting a Metro-integrated light rail train in the median of Interstate 95/395 in Virginia. Through the magic of Google Earth, I give you what I have dubbed "The White Line"

Shown here starting in Woodbridge and terminating at L'Enfant Plaza. The segment up south of the Beltway runs off the freeway along the heavy rail right-of-way. North of that, the line runs in what is now the reversible HOV lanes in the middle of the Shirley Highway.

This stretch of asphalt is one of the most recognizable routes into the city. Ten years ago, I-395 was averaging a quarter of a million in annual average daily traffic. In the last ten years, added lanes and improved intersections have made it easier for cars to travel on this road. But are we making investments to move the most people along this corridor? Could a train move more people quicker than HOV lanes? I bet it would be worth finding out.
