Weekend Road and Rail: Bridge work on the Beltway, I-66 stoppages; Blue line shutdown

This weekend will continue to see work on Interstate 95/Interstate 495 Beltway in Prince George’s County with the bridge work over the Suitland Parkway. Also, overnight full stops on Interstate 66 continue, as does the bridge demolition work on Route 29 in Centreville. And Metro has a 2-week long shutdown planned for the Blue Line.

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



The Maryland Department of Transportation State Highway Administration, MDOT SHA, has been and will continue to do work on the Capital Beltway I-95/I-495 between Allentown Road and MD-4 Pennsylvania Avenue for a bridge replacement over the Suitland Parkway.

There are closures on the shoulders permitted 24/7 through 2021 with intermittent single and multiple lane closures daily and overnights Sunday through Thursday.

On Friday and Saturday nights the hours for single to multiple lane closures will be between the hours of 8 p.m. to 6 a.m.

There are double lane closures scheduled for the Outer Loop from Friday into Saturday overnights between 8 p.m. and 7 a.m. at the current traffic split where two lanes split to the left and two to the right as crews work in the center.

After the traffic shift is complete, all four lanes of traffic will be on the left so that the final stages of the bridge construction can begin in the right lanes.

This project is currently 75% completed with a projected full completion estimated by year’s end 2021, according to MDOT.

Recently, crews have been working on removal of the existing structure on the Inner Loop and are implementing a traffic shift for Outer Loop to start removal for the existing bridge on that side.

In a look ahead, MDOT will close 3 lanes of the Outer Loop over the Suitland Parkway for overnight work Monday and Tuesday between 10 p.m. and 5 a.m.

Starting at 10 p.m., there will be one lane of travel available on the Outer Loop of I-95/I-495 between  Allentown AFB / Morningside, exit 9, and MD-4  Pennsylvania Avenue, exit 11.


The ongoing Transform I-66 Project — which was scheduled to close I-66 for the Gallows Road bridge work this past week — is now scheduled to continue nightly through this weekend, weather permitting.

The overhead utility work on the new Gallows Road Bridge will have lane closures overnight both directions on I-66 approaching Gallows Road, between the Beltway and Vienna Metro, with stops of up to 20 minutes at a time.

Additionally, Gallows Road over I-66 is reduced to a single travel lane nightly with two-way traffic in the southbound lanes.

This is what drivers can expect overnights Friday and Saturday night:

  • I-66 between Cedar Lane to Route 7 (Leesburg Pike) is reduce to one travel lane approaching Gallows Road
  • There will periodic stoppages of up to 20 minutes between midnight and 4 a.m.
  • All lanes should reopen by 5 a.m.
  • This work also closes the ramp from 495 Express Lanes Inner Loop to go westbound on I-66

In Centreville, work is also continuing at the Route 29/I-66 interchange for the remaining demolition of the old I-66 bridge span and piers. This work will require Route 29 Lee Highway to be reduced to a single lane in each direction between 9 p.m. Friday and 5 a.m. Monday.

There will be two-way travel in the northbound lanes starting around 9 p.m. Friday. This traffic pattern will switch around 9 p.m. Saturday to two-way traffic on the southbound side, which will stand for remainder of the weekend.

There will only be single lane travel overnights with flaggers controlling the alternating vehicles and drivers to and from the ramps on I-66 will not be able to make left turns.

The ramp from Route 29 north to I-66 eastbound will be closed for the weekend as part of this ongoing bridge demolition project.

Also overnights, the ramp from Route 28 north to Walney/Braddock Road has been closed between midnight and 4 a.m. for barrier removal with traffic directed farther north to Westfields Boulevard. This work will continue nightly into Saturday morning.

In Vienna, during the overnight hours I-66 east near Nutley Street has had lane closures and stops of up to 20 minutes approaching Vaden Drive for the ongoing overhead bridge work at Vaden Drive. This work is scheduled to continue overnights into Saturday morning 5 a.m.

As always, not all work with these extensive projects and ever-changing configurations will be listed here. Be sure to stay tuned to WTOP news with traffic on the 8s. And, if you see something that’s not being reported, you can call the Traffic Center at 866-304-WTOP.
