The 44th annual Marine Corps Marathon is scheduled to occur October 27 and trigger major street closures and parking restrictions on both sides of the Potomac River. The race kicks off right before 8 a.m. on Route 110 in Rosslyn and will proceed through Palisades, Georgetown, Woodley Park, Foggy Bottom, the National Mall, East Potomac Park, and Crystal City. It ends at the Marine Corps War Memorial, also named the Iwo Jima Memorial, overlooking the city.
A full list of street closures and no-parking restrictions from D.C. police is available here. The traffic changes are expected to last from 2 a.m. to 2 p.m. on a rolling basis. Arlington officials say street closures in the Northern Virginia county will be ongoing between 3 a.m. and 6 p.m.
Metro will open two hours earlier than normal, at 6 a.m., and provide additional service on the Blue and Yellow lines to accommodate marathon runners and watchers. The Pentagon station, which is the closest Metro stop to the starting line, will be exit-only until 8:30 a.m. due to the large number of people expected. The event has a registration of 30,000 runners.
“Additional Yellow Line trains will operate between Huntington and Mt Vernon Sq from 6 a.m. until 9 a.m.; and additional Blue Line trains will operate between Franconia-Springfield and Stadium-Armory from 6 a.m. until 9 a.m. and from 11:15 a.m. until 4:15 p.m,” Metro says in a release. Additionally, the Arlington Cemetery station will be closed until about 8:30 a.m.
