The Dulles Corridor Metrorail Project will be receiving two very large sections of the Wiehle-Reston East Station pedestrian bridges on Thursday, Sept. 20, between 9 a.m. and 2 p.m. The bridge components will be delivered to the median of the Dulles International Airport Access Highway (DIAAH) just west of the Wiehle-Reston East Station.
The work will impact daytime traffic (times are approximate and weather dependent), says the Dulles Corridor Metrorail Project.
10:30 a.m. Two large semi-tractor trailer trucks, each carrying one 16 by 72 foot long bridge section and accompanied by two escort vehicles each, will depart Washington Dulles International Airport and travel east on the DIAAH.
As the trucks approach the Reston Parkway overpass (mile marker 5.2), the escort vehicles will position across the DIAAH and begin to slow traffic down to a "rolling stop." This will allow one of the trucks to pull off the right hand side of the road and stage well onto the shoulder. The other truck will immediately back into the median using the left shoulder and lane.
The "rolling stop" will take approximately 10 minutes, after which traffic will be returned to normal.
1:00 p.m. After the first truck has been unloaded and cleared the area, the escort vehicles will institute a second "rolling stop" to allow the second truck to cross the DIAAH from the right shoulder and back into the median using the left shoulder and lane. Once the truck is off of the road, (approximately 10 minutes), traffic will be returned to normal.
Approximately 12 more deliveries of pedestrian bridge components for the Wiehle-Reston East Station will take place over the next several months.
Once on site, the components will be assembled and prepared for installation across the DIAAH and the Dulles Toll Road (Route 267). The pedestrian bridges will provide access to and from the Wiehle-Reston East Station when the Silver Line begins operation in late 2013.
