Weekend Road and Rail: Greenway closes, Beltway and I-66 stops

Lots of rain is in the forecast this weekend, but if possible, there are planned stops on the Capital Beltway and Interstate 66 as the Transformation Project continues. Corridor work in the District, paving, Purple Line work and updates on Maryland’s Route 32 continue. Metro maintenance will require shutdowns on four lines.

Here’s what you need to know this weekend.



This space, as of late, is generally monopolized by the ongoing Transform 66 Outside the Beltway Project between the Beltway and in Manassas. But heads up, if you plan to travel Route 267/Dulles Greenway on Saturday morning: The westbound Greenway will be closed between Route 28 and Ashburn Village Blvd. for a charity run.

On Saturday, May 7, 2022, the Dulles Greenway will host its 2nd Annual Run the Greenway 5K, 10K and Kids 1-Mile Fun Run.
