The facility is situated in South Dallas, where it serves the Green Line, four bus routes, and a curb-to-curb transit zone.

MLK Jr. station is located at the intersection of Martin Luther King Jr. Boulevard and South Trunk Avenue.

MLK Jr. is one of the City's five prime targets for encouraging mixed-use development near DART; the station area plan released in February 2013 aims to focus growth in an "urban mixed-use area" encompassing vacant lots directly south of the station as well as designating Grand Avenue, Martin Luther King Junior Boulevard and Robert B Cullum Boulevard as corridors to upgrade to complete streets or secondary streetscape areas.

The columns and floor use patterns inspired by Kuba textiles, and two seventeen-foot talking drums flank the entrance to the rail station.
