A meeting to gather the stakeholders involved in paying for the second phase of Metro’s Silver Line has been pushed back by a week because some officials are out of town.

Transportation Secretary Ray LaHood had called last week for those involved in the project — Loudoun and Fairfax counties, Metro, Virginia, and the Metropolitan Washington Airports Authority — to hold a meeting to figure out how to keep the project on track.

The first phase of the new Silver Line is under construction and expected to be completed in August 2013. Construction of the second phase was expected to start early next year.

But getting the process started to put out bids for the second phase has been stalled. MWAA is waiting to see whether Loudoun County supervisors will vote to support paying for the project. The supervisors have until July 4.

LaHood’s meeting is now expected to be held May 2, according to those involved.

The secretary had previously become involved in the Silver Line when he helped negotiate a deal last fall on how the second part of the project would be financed.
