Documents that show some of the inner workings of contract negotiations for the Dulles Corridor Metrorail Project apparently will never see the light of day, according to provisions within a 2004 agreement the state tried, unsuccessfully, to redact.

The comprehensive agreement that guides the entire 23-mile rail extension to Dulles Airport is posted on the rail project’s Web site. Completely blocked out, however, is the section covering the “design-build work” for the first phase of the rail. The Examiner will nevertheless be able to access the information contained in the chapter.
