Weekend Road and Rail: Stops on the Beltway and I-66, Metro shutdowns

Bridge work is planned this weekend that will require full stops on a stretch of Interstate 495 through Tysons in Virginia. The I-66 Transformation project will also see overnight stops along with lane and ramp closures. Metro weekend work is back to include shutdowns on four lines.

Here’s what to know for this weekend.



There are always projects related to the ongoing Transform 66 Outside the Beltway Project that continue into the weekend. But we’re going to start with a scheduled I-495 Express Lanes Project that will have overnight stops related to pedestrian bridge work.

This work is part of the Tysons/Old Meadow Road Bike/PED Improvements to enhance bicycle and pedestrian safety and connectivity in the Tysons area, which includes building a pedestrian and bicycle bridge in the vicinity of Route 123 and I-495/Capital Beltway. The project is scheduled for completion late this summer.

On I-495/Capital Beltway, the general-purpose lanes and 495 Express Lanes will have nightly lane closures on Friday, April 22, and Saturday, April 23, for crews to set the new pedestrian bridge truss.

The lane closures will occur according to the following schedule:

Saturday night, April 23: The three left northbound I-495 general purpose lanes (Inner Loop) between Route 7 and Route 123 will be closed from 10 p.m. to 8 a.m., with full stoppages of up to 20 minutes each occurring between midnight and 5 a.m. On the northbound 495 Express Lanes from 10 p.m. to 8 a.m., the right lane will be closed between Route 7 and Westpark Drive, with full stoppages of up to 20 minutes each occurring between midnight and 5 a.m.
