Leaders at the local and state level in Virginia say they're worried the rising cost of the project will force fees on the Dulles Toll Road to rise painfully high. Money from tolls is paying for a large chunk of the plan to build a new Metro line to Dulles Airport.
Federal Transit Administrator Peter Rogoff says, in the past few days, the McDonnell administration has told him it would contribute an additional $150 million to keep the tolls down.
McDonnell's transportation secretary, Sean Connaughton, won't confirm the offer, but he says it is one of the options under consideration.
Rogoff and other federal officials are working to mediate a dispute over the cost of the project between Northern Virginia's elected leaders and the Metropolitan Washington Airports Authority. Rogoff says if the dispute isn’t resolved soon, it could kill the plan.
