Weekend Road and Rail: Stops on the Beltway and I-66, Greenway closes for race

The weather this weekend will be work-friendly and most projects are expected to be going forward. This means the overnight stops on the Beltway and Interstate 66 in Virginia, 9th Street Tunnel closures in D.C. and of course Beltway work on the Northwest Branch Bridge. But Saturday, there will be a rare closure of the Dulles Greenway for a road race.

Here’s what you need to know before heading out the door in the D.C. region this weekend.

The District Department of Transportation (DDOT) has a daily streetlight inspection project continuing into this weekend. This entails closing lanes and ramps of the 9th Street Tunnel between the hours of 10 a.m. and 3 p.m. Friday through Monday, weather permitting of course.

Motorists traveling during these times can expect:

  • Road closure at entrance to 9th Street Expressway SW from D Street SW
  • Ramp closure from 9th Street Expressway SW that connects to I-395 Northbound SW
  • Left lane closure on I-395 Northbound from 9th Street Expressway SW to approximately between 7th Street SW and 6th Street SW

There will be traffic controls in place to warn drivers approaching these work zones. Motorists should anticipate moderate-to-heavy delays and drivers are advised to stay alert while traveling through these locations and to be observant of the inspection personnel.

This week saw the beginning of a paving project in Northwest along I Street. This repaving work will be daily between 13th Street to Pennsylvania Avenue, Monday through Friday from 8 p.m. to 5 a.m., weather allowing, with a project completion date sometime in late May.

There is a new temporarily project as part of the I-295 Corridor Rehabilitation Project too, which will close single lanes and shoulders along I-295/DC 295 corridor now through about May 15 between 9 p.m. and 5 a.m. nightly.

In Northeast, there are two lane closures on I-295, (Alternating northbound and southbound), between Nannie Helen Avenue Benning Road, nightly through Saturday.


As per usual, into this weekend motorists overnight along I-66 will see a variety of work with ramp, lane and sometimes full closures with myriad projects incorporated in the I-66 Transforms Outside the Beltway Project. But this weekend will see a rare closure for a race on the Dulles Greenway.

Both Friday and Saturday overnights, overhead bridge work at the I-66/I-495 Beltway Interchange will see lane and ramp closures with full traffic stops. Drivers on the I-495 Outer Loop southbound and I-66 westbound should expect delays as both roadways will be reduced to a single lane approaching the I-66/I-495 Interchange each night.

There will be random full stops of traffic up to 20 minutes as well, which are expected to occur several times each night.

There will be a short detour for those traveling on southbound I-495 too, which will push traffic into the I-495 Express lanes at no charge for the detour. During this work, the ramp from I-66 westbound to the I-495 Outer Loop will be closed and detoured as well.

Drivers on the I-495 South/Outer Loop from Route 7/Leesburg Pike to I-66 can expect this work overnights through the weekend between 10 p.m. and 5 a.m., with travel reduced to a single lane and stops of up to 20 minutes.

There are still a few other locations along I-66 seeing overnight ramp and lane closures, which continue into the weekend.

Interstate 66 eastbound is being reduced to two lanes approaching and passing US-50 in Fairfax for overhead bridge work. This will continue through 9 a.m. Saturday, with Route 50 westbound at I-66 having a lane reduced on Saturday between 7 a.m. and 7 p.m.

In Fairfax, there is work continuing at the Route 286-Fairfax County Parkway/I-66 Interchange. The northbound Fairfax County Parkway is reduced to a single lane nightly between US-29 and I-66 between 9 p.m. and 5 a.m.

In Gainesville, I-66 eastbound is reduced to a single from US-29 through Groveton Road. This bridge surveying crew works nightly between 8 p.m. and 5 a.m. and will continue into Saturday morning.

Work continues on US-29 between University and Heathcote boulevards, with travel reduced to a single lane between 8 p.m. 5 a.m.

As these work zones are ever-changing between the Beltway and Gainesville, and with weather disrupting many planned events, a lot of changes can happen during off-peak hours.
