219th

219th refers to a number of military, transportation, and civic entities numbered 219 in their respective naming conventions. In the United States armed forces, the designation appears in several units. The 219th Infantry Regiment is a unit of the United States Army Reserve that has served in both World Wars and in contemporary peacekeeping missions. The 219th Aviation Support Battalion, based in Virginia, provides logistical and support services to aviation units. In France, the 219th Infantry Division was formed in 1914 as part of the Territorial Army and saw action on the Western Front. Other countries have similarly used the ordinal in the titles of their regiments, artillery batteries, or training wings.

The number is also used in transportation routes and infrastructure. U.S. Route 219 is a north–south highway that runs from New York to West Virginia, passing through several major cities and rural communities. In New York City, 219th Street is an east–west arterial road in the Bronx that connects major avenues and provides access to public transit. In other regions, roads, boulevards, and avenues carry the 219th designation as part of their address or traffic planning. Railway stop names and exit numbers on highways sometimes adopt the ordinal number as a way to organize and reference locations.

In civic contexts, 219th is used in the naming of schools, libraries, and city council districts. Some cities number their public buildings, such as 219th Public Library or 219th City Hall, indicating the building’s location or the order in a service plan. This usage reflects the common practice of numbering facilities that share a similar function across a city or region. The term "219th" thus designates a range of entities that share the same ordinal number but vary widely in type and function.
