The Metropolitan Washington Airports Authority on Wednesday insisted that the first phase of the Dulles Metro rail project, which will extend from East Falls Church through Tysons Corner, will be finished on time, despite contractors' projection of a six-month delay, first reported by The Washington Examiner and recorded in a July progress report.

"We are continuing to work very hard to make our expected completion date of Aug. 9, 2013," said MWAA president and CEO Jack Potter. "[Project leaders] have assured me that this project can be brought in on time if we work through some issues."

Dulles commitee chairwoman Mame Reiley urged Potter to sort out the delay before contractors started bidding on the second phase of the project, which is not yet funded.
