What does overpass mean?
An overpass is a bridge or similar structure that carries one route above another, allowing traffic to continue without meeting at ground level. It is especially common in North American English, although British English also uses the term, particularly in infrastructure and transport contexts. The word can also be used as a verb. Literally, to overpass something is to cross above or go over it. Figuratively, it means to ignore a matter or bypass it in discussion or decision-making, often with the implication that the subject has been neglected. The term is useful because it describes both a familiar piece of transport infrastructure and, in its verbal use, a recognizable kind of oversight. The related word “underpass” expresses the opposite arrangement, with one route passing below another.
A bridge or other structure carrying a road, railway, or walkway over another route.
