MD 433 begins at an intersection with MD 410 (Veterans Parkway) in New Carrollton in Prince George's County, heading east on four-lane undivided Ellin Road and immediately leaving the city limits. The route passes through wooded residential areas, curving southeast and then northeast as it becomes a divided highway. The road heads into business parks as it passes northwest of the New Carrollton station that serves Amtrak's Northeast Corridor railroad line, MARC's Penn Line, and the terminus of Washington Metro's Orange Line. MD 433 comes to an intersection with Harkins Road, at which point the road name changes to 85th Avenue. The route narrows to a two-lane undivided road and continues north back into New Carrollton, heading past apartment complexes. MD 433 runs past businesses before it comes to its terminus at an intersection with MD 450 (Annapolis Road), where 85th Avenue continues north as a municipal road.[1][2]
