Ballston-MU is located on the Orange Line (Orange Line), one of Washington DC's operational metro corridors. It sits between East Falls Church and Virginia Square-GMU, making it a convenient stop for the surrounding area.

What makes Ballston-MU particularly useful is its interchange connection with Silver Line. If you need to switch between lines, this is where you'll do it – and you won't need to exit or purchase a new ticket. The interchange corridor is clearly signposted with color-coded directions.
