As crews continue construction for the second phase of the Metrorail Silver Line project, road closures and detours will be along the Dulles Toll Road this week.
Most of the closures avoid prime rush hour times.
The lane, shoulder and road closures started on Monday (Nov. 26) and are scheduled to last until Sunday (Dec. 2), according to a post from the Dulles Corridor Metrorail Project.
The post reminds drivers to use caution; remain attentive to all signage, barricades and speed limits; and obey all police and flagger instructions. Work is subject to weather changes.
Eastbound on Dulles Toll Road has right and left lane closures of varying lengths from west of the Route 28 overpass to the Reston Parkway overpass.
The schedule for this is:
- Monday to Friday: 10 a.m. to 3:30 p.m. and 9 p.m. to 5 a.m.
- Saturday: 10 a.m. to 3:30 p.m. and 8 p.m. to 5 a.m.
There are also three left lane closures with stops every 20 minutes from 10 p.m. to 6 a.m. on Thursday and Friday. Those closures are less than half of a mile west of Centreville Road to the east end of Herndon Station.
Starting at 10 p.m. on Friday, traffic eastbound on Dulles Toll Road near the toll plaza by Route 28 will be detoured to the right lane of the eastbound Dulles International Airport Access Highway. A second right lane will be closed as a safety buffer. Directly after the Centreville Road overpass, traffic will be allowed to re-enter the toll road lanes. This will last until 6 a.m. on Saturday.
Meanwhile, westbound on Dulles Toll Road there are alternating right and left lane closures of varying lengths between the Route 28 and Reston Parkway overpasses.
These will be in effect:
- Monday to Friday: 9:30 a.m. to 3 p.m. and 8 p.m. to 5 a.m.
- Saturday from 10 a.m. to 3:30 p.m. and 8 p.m. to 5 a.m.
Drivers heading westbound on the road will also experience three left lane closures with 20-minute stops from almost a quarter of a mile west of Van Buren Street to the west end of Innovation Center Station at 6 a.m. on Saturday and Sunday.
Herndon Parkway East has a right lane closed 1,000 feet east of Van Buren Street to 800 feet west of Exchange Place. This takes place from 9:30 a.m. to 3:30 p.m. from Tuesday until Thursday and then from 9:30 a.m. to noon on Friday.
Other roads affected include the Dulles International Airport Access Highway, Autopilot Drive, Dulles Greenway, eastbound on Sunset Hills Road East, westbound on Sunrise Valley Drive and southbound on Moran Road.
