Flyover vs. Overpass
“Flyover” and “overpass” are regional equivalents when they mean a bridge carrying one route over another. “Flyover” also has a separate aircraft-event sense, especially in American English.
For the road-bridge sense, UK “flyover” corresponds to US “overpass”; US “flyover” also has an aircraft-event meaning.

Quick tests
Meaning / construction test
Are you naming a road bridge, and is the copy aimed at a specific regional variety?
If yes: Use “flyover” for UK-oriented road copy or “overpass” for US-oriented road copy.
If no: If you mean aircraft passing overhead, “flyover” has that separate sense.
Caveat: The road-term distinction is regional rather than a universal correctness rule, and US “flyover” also has a distinct aircraft meaning.
Examples
Take the second exit after the flyover.
“Flyover” is the UK-oriented road term.
Turn left just beyond the overpass.
“Overpass” is the US-oriented road term.
The ceremony included a military flyover.
Here “flyover” refers to aircraft passing overhead.
Further guidance
Core difference
In the road-bridge sense, “flyover” is chiefly UK and “overpass” is chiefly US.
Fast Test
For a grade-separated road bridge, choose “flyover” for UK-facing prose and “overpass” for US-facing prose.
Usage Boundary
Do not assume every “flyover” is a bridge: American English also uses “flyover” for an aircraft display, where British English often uses “flypast.”
