Weekend Road and Rail: I-66 sees 3 stops; Metro works on all lines with 2 shutdowns

There are two planned shutdowns for Metro this weekend and three locations of Interstate 66 will see full stops. There is still Beltway and bridge work in Maryland, plus paving and road projects in the District. Here’s a look at a few things planned for this weekend, weather permitting.

Here’s what you need to know if you’re traveling in the D.C. region this weekend.



As to be expected, the continual work on the I-66 Transforms Outside the Beltway Project will see more changes and reconfiguring into this weekend.

Starting in Centreville, this week has seen much focus on the bridge beam installation project at Route 28 and I-66, which is scheduled to continue into this weekend, weather permitting. There is a chance for storms overnight Saturday, so be sure to stay tuned to traffic on the 8s for the latest.

Most of this work has been taking place since the middle of the week, but here’s a recap of what will be planned as far as lane and ramp closures through this weekend.

There continues to be full closures and detours planned for I-66 at Route 28, which has been the case all week. VDOT said that’s the plan through overnight Friday from between approximately 9 p.m. and 4:30 a.m.

During this time all westbound I-66 traffic will be diverted to Route 28 north toward Westfields Boulevard to follow the posted detour signs for a U-turn back to I-66 West.

This reconstruction is to improve traffic flow on I-66 and Route 28 and provide access to and from the future I-66 Express Lanes. The I-66 Outside the Beltway Express Lanes, which span from Interstate 495 to Route 29 in Gainesville, are expected to open in December 2022.

There will be ramp changes for the Route 28/I-66 Interchange work as well. As to be expected with this work, the ramp from I-66 East to northbound Route 28 will be closed. On Route 28 north between I-66 and Walney Road there will be two lanes closed through 5 a.m. Saturday morning.

On I-66 East from Route 29 through Route 28 there will be three lanes closed both Friday and Saturday nights from 9 p.m. to 9 a.m. as part of the bridge beam work. This closure will allow crews to implement a new traffic shift.

The work at Route 29 and I-66 in Centreville is scheduled to continue this weekend too. Crews will close the ramp from Route 29 northbound to I-66 West continuously, for the entire weekend beginning Friday at 10 p.m. through 5 a.m. Monday.

All traffic will be detoured to the Trinity Parkway/Machen Road interchange to make a U-turn. The ramps from Route 29 to I-66 East will be closed and detoured on Saturday night between 11 p.m. and 4 a.m. Sunday as well.

Moving farther west on I-66, there is survey and paving work planned overnight Friday from 9 p.m. and 7 a.m. On westbound I-66 from Route 29 toward Manassas there will be 3 lanes closed. And eastbound I-66 from the Prince William Parkway through Route 29 in Centreville it will be the same.

In Fairfax, the work remains much the same. The overnight bridge demolition at the Route 50/I-66 interchange will continue through this weekend.

On I-66 westbound at Route 50, all lanes are closed and diverted to Route 50 West for a U-turn at the next intersection, West Ox Road. This overnight work is scheduled Friday and Saturday between 11 p.m. and 6 a.m.

During this time, the ramp from I-66 West to Route 50 East and the ramp from Route 50 West to I-66 West will both be closed and detoured too.

As we move eastward, there is still interchange work at Route 123, which will have lanes closed overnight Friday. The ramps from Route 123 to I-66 East will be closed and detoured from midnight through 4 a.m. Saturday.

And on Route 123 north between Eaton Place and I-66 there will only be a single lane of travel available as crews implement a new traffic shift between 9 p.m. and 5 a.m.

There are two other locations on I-66 where crews will be planning a complete stop overnight for overhead bridge work. On I-66 East between Route 123 and Nutley Street there will be three lanes closed overnight Friday and Saturday between 9 p.m. and 6 a.m.

During this time, motorists should be advised there could be random periodic stops of up to 20 minutes at a time. And the ramps from Nutley Street to I-66 East will remain closed through 7 a.m.

Moving closer to the Beltway, work is planned in both directions of I-66 overnight Friday between about 9 p.m. and 5 a.m. From Nutley Street to Gallows Road, there is planned utility work with both directions seeing 3 lanes closed and stops of up to 20 minutes at a time.

Eastbound I-66 from Gallows Road toward the Beltway the three-lane closure extends for equipment mobilization as well.

At the Beltway, the Express Lanes work will continue to have ramp changes overnight from 10 p.m. through 5 a.m. Saturday. The ramps from I-66 East to I-495 Express South and from I-495 Express Lanes north to I-66 West will both be closed and detoured via overhead signage.
