After $210-million in value engineering, the proposed $5-billion, 23-mile extension of Washington, D.C.'s metrorail system to Dulles International Airport is back on track.
The Federal Transit Authority announced April 30 that the project met sufficient criteria to move forward to final design—a reversal of FTA's previous position. The U.S. Department of Transportation raised several technical, financial and management concerns in January, and said the project was “insufficient to advance” as proposed.
