The term "beltway" is primarily used to refer to a highway or a ring road that encircles a city or urban area. It is typically designed to efficiently connect different areas within the city and aid in traffic flow, creating a complete loop that circles the core districts. Beltways are commonly constructed in metropolitan regions to divert through-traffic from the city center and reduce congestion.
The name "beltway" comes from the circular shape of these roads, resembling a belt or a loop that encircles the city. Beltways are often characterized by multiple lanes, allowing for a smoother traffic flow and higher speed limits. They also serve as major transportation arteries, connecting radial roads or highways leading into the city from various directions.
Beyond their infrastructure, the term "beltway" has gained a figurative meaning in political contexts. Specifically, it refers to the driven and self-contained world of politicians and bureaucrats in the capital city, often detached from the reality and concerns of ordinary citizens. This usage alludes to the prominent role of beltways around capital cities, such as the Washington D.C. Beltway, in hosting government institutions and headquarters of political power.
