Maryland Route 202
state highway in Prince George's County, Maryland, United States
Maryland Route 202 (MD 202) is a state highway in the U.S. state of Maryland. The highway runs 13.92 miles (22.40 km) from MD 725 in Upper Marlboro north to MD 450 in Bladensburg. MD 202 connects the central Prince George's County communities of Bladensburg, Cheverly, Landover, and Largo with the county seat of Upper Marlboro. The state highway was constructed from Bladensburg to Largo in the mid- to late 1920s and from Largo to Upper Marlboro in the early 1930s. MD 202 was relocated through Landover in the early 1940s. The highway was expanded to a divided highway with several interchanges from Bladensburg through Landover and Largo from the early 1960s to the mid-1970s. In the 1990s, MD 202's divided highway segment was extended halfway to Upper Marlboro and expanded again through Largo, including the construction of several auxiliary routes to connect the highway with Northwest Stadium.

Why this record matters
The subject matters to the places & architecture register because the source frames it as state highway in Prince George's County, Maryland, United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jan 26, 2026. The linked authority identifier is Q2480199. VIAF identifies the subject as 315528428. The Library of Congress control number is sh98006319. Authority coordinates are 38.891, -76.825. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
