Potomac Ave is located on the Orange Line (Orange Line), one of Washington DC's operational metro corridors. It sits between Eastern Market and Stadium-Armory, making it a convenient stop for the surrounding area.

What makes Potomac Ave particularly useful is its interchange connection with Silver Line, Blue 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.
