Columbia Heights is located on the Yellow Line (Yellow Line), one of Washington DC's operational metro corridors. It sits between U Street/African-Amer Civil War Memorial/Cardozo and Georgia Ave-Petworth, making it a convenient stop for the surrounding area.

What makes Columbia Heights particularly useful is its interchange connection with Green 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.
