Lanes will begin to taper down near the Route 7 (Leesburg Pike). All ramps to and from Route 123 will remain open, except for the ramp from southbound Route 123 to southbound I 495, which will be in the overnight hours from Thursday, June 9 to Tuesday, June 14.

Eastbound Dulles International Airport Access Highway (DIAAH) to Close Overnight Four Nights Next Week; Detour on to Westbound Lane The eastbound lanes of the Dulles International Airport Access Highway (DIAAH) will be overnights Wednesday, June 8 Saturday, June 11, from approximately 8 to 5 a.m. The closing is necessary because rail construction crews will be working on a large concrete structure that will straddle two piers on each side of the eastbound DIAAH. The exit to Route 7 (Leesburg Pike) will remain open.

All times are approximate: 7 The left lane of the westbound DIAAH will close near Route 7. 7:30 The right lane of the eastbound DIAAH also will close near Route 7. 8 All eastbound DIAAH traffic willl be diverted on to a single westbound lane, which will remain open to accommodate diverted Toll Road traffic (see listing below). At this time, westbound DIAAH will be two way traffic. Closures will be picked up in reverse order, to be completed at 5 a.m. the following mornings. This work is expected to occur intermittently as needed through the end of July. Eastbound Dulles Toll Road (Route 267) Also to Close Two Nights Next Week For two nights next week, closures on both the Dulles Toll Road and the Dulles International Airport Access Highway are scheduled. The previously announced DIAAH detour (see details above) will be combined with a closing and detour of the eastbound Dulles Toll Road, also near Route 7.
