Drivers using Route 606 and Mercure Circle just west of Dulles Airport may experience some slow traffic beginning Jan. 13, due to a rock removal (blasting) operation taking place at the site of the Silver Line's future Rail Yard and Maintenance Facility. The operation is expected to be complete by the end of March 2016.
On Wednesday, Jan. 13, 2016, Hensel Phelps, the Rail Yard contractor, will conduct a test blast to evaluate the vibration levels, sub-grade and sub-drill requirements. The operation will last approximately 8 - 10 weeks. Weekly blasting operations will occur daily, Monday through Friday, between the hours of 2 p.m. to 2:30 p.m. On Fridays, blasting will not occur if in close proximity to Route 606 or Old Ox Road requiring traffic stoppage.
What to expect: There will be a long warning signal for the duration of 1 minute, 5 minutes prior to each blast. If blasting is in close proximity to Route 606 or Old Ox Road, nearby traffic will be stopped by flagmen 1 to 2 minutes before the blast. Traffic will resume shortly after the operation is complete. A total wait time of 2 - 3 minutes is expected.
Please see the map below which shows the location of specific blast areas on the project site. Again, flagmen will be on site for potential traffic stops.
