Rosslyn is one of the most highly concentrated places of activity in Arlington.  It is where thousands of employees come to work each day, from all directions throughout the Metropolitan Washington region and beyond.  At night, Rosslyn's Metro Station continues to bustle, and many residents who call Rosslyn home return to the district well into the evening hours.  Rosslyn is more and more becoming a place where people work, live and play and  because of this, The Washington Metropolitan Area Transit Authority (WMATA, or Metro) currently has a plan for a second Rosslyn Metro station.
