From NBC4 (this is the entire piece): "There could soon be a faster way to get from Prince William County to the District. The Potomac River Express commuter ferry took its first test run Thursday, traveling from Quantico Marina up the Potomac River to Navy Yard. During the trial run, the ferry got to the Wilson Bridge in 47 minutes. The ferry arrived at
Navy Yard in just under an hour. That's nearly half the amount of time it can [take] by car during rush hour. More test runs for the ferry are planned for the spring. The company that will run it still needs to get approval to operate from the Virginia Department of Transportation." There's also a much more detailed story from the
Potomac News. I don't think they actually docked anywhere along the Anacostia (since there isn't anywhere for a ferry to let people off--yet), they were just testing the time.
