Silver Line Phase 2 Windscreen Updates Progress at Dulles Airport Station

Marcia McAllister Tysons Update

Structural steel erection work is complete on the north and south sides of the Dulles Airport Station. The steel will support louvers on the north side of the station and the glass windscreen on the south side facing the main airport terminal. Once the contractor, W.M. Schlosser Co., completes welding work, crews will begin applying the steel coating system and install the glass screenwall and louvers. Louver and glass deliveries are scheduled for June as long as there are no COVID-19 manufacturing issues.

The Dulles Corridor Metrorail Project agreed to comply with more stringent stormwater requirements that were implemented after the project was approved. This stormwater pond southwest of Herndon Station will not only retain, but also treat stormwater before it reenters the Chesapeake Bay watershed.
