Overnight Detour for
Westbound Dulles International Airport Access Highway
Friday, Jan. 26 - Saturday, Jan. 27, 10 p.m. to 6 a.m.
Saturday, Jan. 27 - Sunday, Jan. 28, 10 p.m. to 6 a.m.
 
On Friday, Jan. 26 - Sunday, Jan. 28, from 10 p.m. to 6 a.m. each night, drivers using the westbound Dulles International Airport Access Highway (DIAAH) will experience a detour to the westbound Dulles Toll Road between Beulah Road and Route 28 while Dulles Corridor Metrorail Project crews continue the construction of the Innovation Center Metrorail Station in the median of the DIAAH. This detour is dependent upon wind and weather advisories.  See details below and on the next page. 
 
WESTBOUND DIAAH: 
  • From 10 p.m. to 6 a.m., the slip ramp from the westbound DTR to the westbound DIAAH at mile marker 9.0 (2/10 mile past the Beulah Road overpass) will be closed. All westbound DIAAH traffic will be diverted to the westbound DTR via the bus ramp at mile marker 8.3 (see Figure 1).
Figure 1:  Traffic on the WB DIAAH will be diverted to the WB DTR near mile marker 8.3.
  • Westbound traffic to the airport will return to the DIAAH via the slip ramp at mile marker 1.8 with no toll payment required (see Figure 2).
             Figure 2:  Airport Traffic will re-enter the WB DIAAH at mile marker 1.8.
 
All work is wind and weather dependent and subject to change.   
Drivers are asked to use caution and pay attention to all signage and barricades. Large, slow-moving vehicles may be exiting and entering the highway at various times.
