WASHINGTON (AP) — A final deal hasn’t been reached to move forward with the second phase of Metro’s planned Silver Line expansion, which would link up with Dulles International Airport.

That’s according to a Washington Post story quoting Transportation Secretary Ray LaHood. The newspaper reports that Lahood said a meeting on the Silver Line did yield some progress.

Virginia Transportation Secretary Sean T. Connaughton, chairmen of Loudoun and Fairfax counties’ boards of supervisors, and officials from Metro and the Metropolitan Washington Airports Authority joined LaHood for the meeting.

Labor issues, incentives and the project’s pricetag are part of the dispute.

LaHood still believes the project will move forward.

The Silver Line’s first phase, which runs through Tysons Corner to Wiehle Avenue, is under construction and expected to be completed next year.
