Weekend Road and Rail: DC festivals return; new Metro shutdown; I-66 and I-295 transformations

Unlike last weekend when the remnants of Hurricane Ida barreled through the region, it doesn’t look like weather will be a factor for roadwork this weekend.

The District will see the return of a few annual events complete with street closures. Meanwhile, on the outskirts of town, work on Interstate 66, the Beltway and Metro’s Purple Line continues.

Here’s what to know:



We are looking at a mostly clear weather weekend, which bodes well for the ongoing Transform 66 Outside the Beltway Project, with a big change scheduled first thing Friday morning.

During the overnight hours into Saturday morning, lane closures will take place on the Outer Loop of the Beltway, or southbound Interstate 495 approaching I-66. There are only two travel lanes, with multiple 20-minute traffic stops for bridge beam installation.

The ramps from I-495 South to I-66 West, and from I-66 West to I-495 South, are also closed in conjunction with this work, which takes place between 10 p.m. — 5 a.m. nightly.

Here is a look at the detours for these closures:

This I-66/I-495 Interchange project continues to be modified with several new ramps and connections as part of the larger transformation project.

Also overnights through Sunday, crews are continuing demolition of the old Route 50 bridges over I-66 in Fairfax. This requires the ramp from Route 50 East to I-66 East to be closed between midnight — 4 a.m. Traffic will be directed further west for a U-turn during this time.

On I-66 approaching Route 50, three lanes will be closed through Friday nights for crews to implement traffic shifts. On Saturday night, two lanes will be closed. Drivers should expect periodic stoppages during the overnight hours, which will occur in both directions.

There is also overnight work in both directions approaching Nutley Street, the overhead bridge work here has three lanes closed eastbound and two westbound between 9 p.m. through 9 a.m., Saturday morning with periodic stops planned.

Overnight work has been continuing this week at the I-66/Stringfellow Road Interchange. Here, too, the work will take place nightly through Sunday morning, with lanes reduced to a single lane of travel any time between 10 p.m. — 6 a.m.

As always, all work scheduled is weather dependent and subject to change, and many other projects could hamper your travel. Stay tuned to WTOP traffic on the 8s for the latest.

The Maryland Department of Transportation State Highway Administration (MDOT SHA) began its work this week to resurface the I-495 Capital Beltway in Silver Spring, Montgomery County.

Crews will perform nightly milling, paving and marking on I-495 between MD 97/Georgia Avenue and MD 185/Connecticut Avenue nightly from 9 p.m. — 5 a.m., working Sundays through Fridays each week, with completion projected this fall.

During the resurfacing, crews will work simultaneously on the Inner and Outer loops of I-495 to expedite the project. Once resurfacing is complete, crews will continue painting the new Seminary Road Bridge replacement using off-peak overnight work hours.

Travelers on the Beltway during this time can expect single and multiple lane closures, which can cause delays. There will also be off-peak work requiring single and multiple lane closures weekdays, 9 a.m. — 3 p.m., for additional work related to the project.

There is also work on the Beltway between Suitland Road and MD 4/Pennsylvania Avenue, with lane closures for ongoing bridge rehabilitation. More information on the bridge work can be found here.

Also, in Prince George’s County, motorists can expect work at the MD 410/Baltimore-Washington Parkway interchange with daily closures through the end of the month.


This weekend will see the return of Fiesta DC, an annual celebration highlighting Latino culture with a parade of nations, kid’s festival, food, crafts and more. The festival-related street closures run all weekend and include Pennsylvania Avenue NW, between 7th Street and Constitution Avenue, and continue through 3rd Street, with parking restrictions and a parade on Sunday.

This Sunday will see the return of the annual Cherry Blossom 10 Mile Run and 5K Run-Walk, which was rescheduled due to the pandemic. This annual elite race will close roadways around the National Mall.
