Traffic stops planned on Dulles access road If you're bringing back passengers from Dulles International Airport at midday Thursday, pay attention to this planned disruption on the eastbound Dulles Airport Access Highway. Two very large sections of the pedestrian bridges for the Wiehle-Reston East station on the Silver Line are scheduled to arrive at the station by truck. They will be delivered to the median of the access highway, east of the airport at mile marker 7.4. Getting the trucks into the station area in Reston will require two traffic stops, one in the morning and one in the early afternoon. This is the sequence, if all goes according to plan for the Dulles Metrorail project: Two large trailer trucks, each carrying a bridge section, will leave the airport and drive east on the access highway. As the trucks approach the Reston Parkway overpass, their escort vehicles will spread out across the access highway and begin to slow traffic. One of the trucks will pull off the right hand side of the highway and get onto the shoulder. The other truck will immediately back into the median, using the left shoulder and left lane. This should take about 10 minutes. Then the traffic flow will return to normal. 1:00 p.m. After the first truck is unloaded, the same procedure will be used to get the second truck into the station area. The escort vehicles will again spread across the eastbound access highway It should again take about 10 minutes to get the truck from the right shoulder into the highway's median. Over the next several months, this will happen about 12 more times, to get all the parts of the bridge into the station. When assembled, they will stretch across both the access highway and the Dulles Toll Road to get riders on the new Silver Line into the station after it opens late next year.
