Maryland Route 202 begins in the south at an intersection with MD 725 in Upper Marlboro, close to US 301. As a two lane road carrying the name Largo Road, it turns north, crossing the Collington Branch and passes through a long patch of forested land. Various areas of suburban residential development are located off this road on side streets. After emerging from the forest, MD 202 dualizes and becomes a four-lane road. In Kettering it interchanges with MD 214 (Central Avenue), and after intersecting Saint Joseph's Drive the road's name changes to Landover Road.

Turning and beginning to follow a more western trajectory, the route then interchanges with the Capital Beltway at what is locally known as "The Fountain" in a tribute to the former Landover Mall, as its fountain and logo were inspired by the Exit 17 cloverleaf where 95 and 202 intersect. Now entering Landover, the route features sidewalks, continuing across Maryland Route 704 (Martin Luther King, Jr. Highway) and then the Orange Line of the Washington Metro, followed shortly after by and interchange with US 50. Residential development grows closer to the road here as it then interchanges with the Baltimore–Washington Parkway The route then ends at an acute intersection with MD 450 in Bladensburg.
