Three days next week officials will test a ferry run on the Potomac River between Prince William County and Southwest D.C.
The time of the trip, possible stops and commuter interest will be evaluated.
The ferry idea has been talked about for about five years. Prince William Supervisor Frank Principi, D-Woodbridge, says officials conducted test runs two years ago.
"We consistently did 55-minute runs from Quantico up to the Navy Yard," he says.
The route under consideration includes as many as eight stops in Virginia, three stops on the Maryland shoreline and two on the Southwest waterfront, including one at Nationals Park.
The ferry's can carry about 149 people.
