if you are planning on flying into Ronald Regan National Airport this Labor day weekend, and taking the Metro subway: warning, it will be closed. Track maintenance will close three stations along the Blue and Yellow lines Labor Day weekend. Pentagon City, Crystal City and Reagan Airport metro stations will be closed from 9:30pm Friday September 4th until 5am Tuesday September 7th.
Metro will have free shuttle bus service for those riders who need to get to any of the closed stations.
My experience is that these are few and far between plus a real cattle call rush to board with many many frustrated people left behind,
Just a heads up to visitors: plan on taking a cab as metro subway will for all intent and purposes not be available. A good excuse just to stay in Old Town and enjoy yourself
