The state highway begins at a dead end adjacent to the Baltimore–Washington Parkway.

MD 769D heads north as a two-lane undivided road through an industrial area, crossing the Alexandria Extension of CSX's Capital Subdivision railroad line at-grade before reaching its northern terminus at MD 201 (Kenilworth Avenue).

The state highway begins as 52nd Avenue a short distance north of MD 769D's northern terminus.

The state highway meets Quincy Street on a tangent and assumes that name, then turns north and becomes 48th Street at the intersection with an unnamed road that provides access to northbound MD 201.

[5] The portion of MD 205 from Bladensburg to Riverdale Park was constructed as a 15-foot-wide (4.6 m) concrete road between 1924 and 1926.

[11][12] Construction on modern MD 201 as a divided highway from Washington to Greenbelt began in 1952.
