McLean, Va. – The National Park Service is planning to close the southbound lanes of the George Washington Memorial Parkway from Tulane Drive to Morningside Lane between 8:00 a.m. and 3:30 p.m. to allow for tree maintenance on October 1, 2, 6, and 7, weather permitting. Traffic will be diverted onto Park Terrace during this period.

These closures support the National Park Service’s mission to preserve safe access to the parkway while protecting the scenic and natural resources along the Potomac River corridor. This is part of the park’s larger efforts to conduct tree maintenance along the George Washington Memorial Parkway between Mount Vernon and just south of Alexandria.

The National Park Service is making every effort to limit these disruptions during peak rush hour travel.

The National Park Service appreciates the public’s patience while this important safety work is completed.
