11/20/17

Loudoun County officials announce upcoming planned nighttime lanes closures and detours on the Dulles Greenway to accommodate the installation of structural steel for the Route 772 Transit Connector Bridge on the Dulles Greenway. The work is scheduled to begin the night of Monday, November 20, 2017, and continue through Wednesday, December 20, 2017, weather permitting. Law enforcement personnel will be onsite during the work. Electronic signage also will be in place prior to, and during, any lane closures or detours.

The Route 772 Transit Connector Bridge will be located between Exit 6, Ashburn Village Boulevard, and Exit 7, Loudoun County Parkway, on the Dulles Greenway. The bridge will be the extension of the existing Metro Center Drive and will span the entire Dulles Greenway to provide access to the north and south Silver Line Metro Parking Garages, as well as all other infrastructure and roadways in that vicinity. The bridge will have a shared use path for pedestrian traffic, as well as north and southbound lanes for vehicular traffic. 

The construction work is divided into four phases:

  • Phase 1: Scheduled to begin the evening of Monday, November 20, and continue through Wednesday, November 22, 2017. This work will affect the eastbound lanes of the Dulles Greenway.  From 10:00 p.m. to 4:00 a.m., two right lanes will be closed and there will be intermittent full lane closures of up to 20 minutes for offloading and placement of steel girders. 

  • Phase 2: Scheduled to begin the evening of November 27 and continue through December 1, 2017. The work will cause a number of lane closures and detours on the east and westbound lanes of the Dulles Greenway from 7:00 p.m. to 10:00 p.m., and 10:00 p.m. to 5:00 a.m., November 27, 28 and 29, and from 10:00 p.m. to 5:00 a.m., November 30 and December 1, 2017. 

  • Phase 3: Scheduled to begin the evening of December 4 and continue through December 7, 2017. Lane closures will occur on the westbound lanes of the Dulles Greenway from 7:00 to 10:00 p.m. A full detour will occur on the westbound lanes from 10:00 p.m. to 5:00 a. m.
  • Phase 4: Scheduled to begin the evening of December 8 and continue through December 20, 2017, with double lane closures from 10:00 p.m. to 5:00 a.m. on both the east and westbound Dulles Greenway.
