The eastbound Dulles Access Highway (DIAAH) will be closed between Centreville Road and Fairfax County Parkway from Friday (August 3) at 10 p.m. through Monday (August 6) at 5 a.m.
Traffic from the eastbound lanes will be diverted to the left lane of the eastbound Dulles Toll Road and will then be returned to the DIAAH once past the construction area. The closure is necessary to allow Dulles Corridor Metrorail Project crews to complete storm drain work in the area.
DIAAH drivers will not have to pass through any toll both on the toll road during the detours. Eastbound toll road traffic will be restricted to two lanes. All drivers are strongly encouraged to exercise caution and pay attention to all signs and barricades.
