Overnight Detours and Ongoing Short-term Stoppages on Eastbound Dulles Greenway

Saturday, August 13 - Sunday, August 14

On or about Saturday, Aug. 13 at 10 p.m., and continuing until Sunday, Aug. 14 at 8 a.m., the eastbound Greenway at mile marker 11 near the Old Ox Road overpass will be detoured to eastbound Old Ox Road (Route 606) while Dulles Corridor Metrorail Project crews construct a large concrete span for the Silver Line Aerial Guideway, over the eastbound lanes. Traffic to Dulles International Airport, the Dulles Airport Access Highway (DIAAH), and the eastbound Dulles Toll Road (DTR) will follow eastbound Old Ox Road to southbound Route 28. See Figure 1 for details.
