The Concourse Line is a subway branch line of the New York City Subway system, extending from 205th Street in the Norwood section of the Bronx to join with the Eighth Avenue Line at 145th Street in the Harlem neighborhood of Manhattan. The line runs from 205th Street in a generally south and south-westerly direction, running beneath the Grand Concourse roadway for much of its route, from which it derives its name.
