Weekend Road and Rail: I-66 bridge demolition; closures on DC-295; Metro work on all lines

Work is continuing all around our region during the summer, with thunderstorms in the forecast, too.

Metro is doing work on all lines this weekend. And, weather permitting, here is a look at what’s planned for Virginia, the District and Maryland:



There are some changes in the forecast for the Transform I-66 Outside the Beltway project. Not only is work continuing with a bridge demolition in Fairfax and Centreville, but crews will also be working to implement yet another shift beginning next week. We’ll look at what to watch for this weekend, but always remember, things are fluid, so be sure to stay tuned to traffic on the 8s for the latest.

The overnight bridge demolition at the Route 50/I-66 interchange has been happening this week and is slated to continue into the weekend. This work has called for full closures of I-66 heading westbound with diversions on Route 50 and ramps closing in all directions at the interchange. This overnight work, which is being scheduled into Sunday morning, is a continued demolition of the Route 50 East bridge over I-66. The westbound bridge demolition was completed last week.

On Friday night and early Saturday morning, the work pattern will be different than that of the rest of the weekend. From about 10 p.m. to 5 a.m., there will be two-way travel on the interstate essentially to and passing Route 50 in both directions. This work will be controlled by flaggers with police on site for traffic control.

Throughout the weekend, to perform the eastbound Route 50 bridge demolition work, crews need to block all lanes and will divert westbound traffic on I-66 to Route 50. The traffic diverts to westbound Route 50 toward Route 608/West Ox Road for a U-turn return. This will continue nightly between 11 p.m. and 5 a.m. Also for the weekend, all lanes are scheduled to reopen by 6 a.m. The ramps from Route 50 West to I-66 West will be closed and detoured.

Also during this time, the eastbound lanes of I-66 approaching Route 50 will be reduced to two lanes until reopening on Monday by 4 a.m.

Also scheduled again through this weekend is the work in Centreville on Route 29 under I-66, with lane reductions and flaggers for bridge beam installation as part of the Transform 66 project. This work, which has been happening nightly between 9 p.m. and 4 a.m., is scheduled to continue through Monday morning, with some changes left in place for the entire weekend.

During Friday and Saturday nights, Route 29 will again be reduced to a single lane of travel, alternating directions with traffic controlled by flaggers. During this time, there are no turns allowed, so be sure to plan accordingly. This weekend, a few configurations and times from this week’s work will be slightly different. Here’s what to expect on Route 29 at I-66 this weekend:

  • Work begins 9 p.m. Friday through 4 a.m. Monday.
  • Route 29 will be reduced to a single travel lane in each direction.
  • Two-way traffic will run in the northbound lanes of Route 29 under I-66 from 9 p.m. Friday through around 6 p.m. Saturday.
  • Two-way traffic will run in the southbound lanes of Route 29 under I-66 from around 6 p.m. Saturday through 4 a.m. Monday.
  • Flaggers will alternate traffic on one lane of Route 29 in the overnight hours of Friday and Saturday from 10 p.m. to 8 a.m.
  • There will be periodic stoppages of up to 20 minutes on weekend overnights.
  • All lanes are scheduled to reopen by 4 a.m. Monday.

This work will also dictate the ramps traveling at this interchange and motorists will see that continue into the weekend, with the ramps to and from I-66 and Route 29 closed and detoured. Continuous lane reductions are expected through this weekend, weather permitting, so be prepared for varying message boards and travel directions daily.

These are only a few of the changes and work zones that will take place this weekend. The I-66 project is broad and ever-changing. There is also work planned overnight with ramp closures at I-66 interchanges at the I-495 Beltway Express Lanes, Nutley Street, Route 123/Chain Bridge Road and Route 50. Plus, stay tuned to learn about all of the other work locations that may pop up for the weekend.

As always, all work is weather dependent and subject to change, so stay tuned to WTOP Traffic on the 8s for the latest. And be sure to call the 24/7 Traffic Center at 866-304-WTOP to help with changes, variations and be part of the team.
