Overnight Detours on Eastbound and Westbound DIAAH
10 p.m. Tuesday, May 31 - 5 a.m. Wednesday, June 1
On or about Tuesday, May 31 at 10 p.m., and continuing until Wednesday, June 1 at 5 a.m., the eastbound and westbound Dulles International Airport Access Highway (DIAAH) at Dulles International Airport between mile markers 0.0 and 0.4 will be detoured to the Aviation Drive ramps to facilitate construction of the Silver Line's aerial guideway. 
Left lane closures on the eastbound and westbound DIAAH will begin at 9 p.m. with all traffic detouring to the Aviation Drive ramps at 10 p.m. See Figure 1 for details.
On subsequent nights throughout the spring and summer months, night time lane closures and detours of the eastbound DIAAH will be utilized, and westbound DIAAH traffic will be reduced to a single lane and diverted around the work area as needed. Traffic on the ramp from eastbound Aviation Drive to the terminal will stop before merging with westbound DIAAH traffic. See Figure 2 for details.
Police will be present along Aviation Drive to give priority to terminal traffic.  Drivers should exercise caution, pay attention to barrier and signage and obey all police and flagger instructions.
All work is weather dependent and subject to change.
