Ongoing and weather permitting, workers will continue to repair a sinkhole south of I-495 at Dead run. Until the work is complete, the right lane on the northbound side of the parkway is closed near the affected area. This work will likely require planned closures of both northbound lanes and a single southbound lane. The NPS is committed to keeping people informed and will share more information once details are finalized.

Drivers should expect occasional off-peak hour lane closures on the southbound side of the road so that workers can continue inspecting and repairing the road drainage system.

The closures are scheduled to begin at 7:30 p.m and end at 4:30 a.m. The lane closures are needed to complete the Key Bridge Rehabilitation Project.

The project’s completion date has been extended.

[ONGOING] Parkway pothole repair

Ongoing and weather permitting, crews are working to repair potholes along the Clara Barton and George Washington Memorial Parkways. Use caution in these areas and follow workers’ instructions.

[ONGOING] Staging area construction traffic for Arlington Memorial Bridge rehabilitation

The work will happen during the day and flaggers will direct traffic during temporary lane closures as trucks deliver material there. These closures will also affect the Mount Vernon Trail. The trail will not close, but users may have to wait while workers move material over it. Drivers, pedestrians, and cyclists should watch for flaggers who may be directing traffic while the work is going on. Learn more at
